Answer:

6 1/2

Step-by-step explanation:

[tex]2 \frac34 + 3\frac34[/tex]

Convert them to improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, then putting it over the denominator:

[tex]2 \frac34 + 3\frac34=\dfrac{2 \times 4+3}{4}+\dfrac{3 \times 4+3}{4}=\dfrac{11}{4}+\dfrac{15}{4}[/tex]

As the fractions have the same denominator, we can simply add the numerators:

[tex]\dfrac{11}{4}+\dfrac{15}{4}=\dfrac{11+15}{4}=\dfrac{26}{4}[/tex]

Convert back to a mixed number by dividing the numerator by the denominator. Writing the whole number followed by the remainder over the denominator:

[tex]\dfrac{26}{4}=6\frac24=6\frac12[/tex]

Answer:

It will 26 weeks to save for the cruise starting from a balance of $140

(It will take 30 weeks in total, if you start saving from $0)

Step-by-step explanation:

let x = number of weeks

Given starting balance = $140

⇒ 140 + 35x = 1050

⇒ 35x = 1050 - 140

⇒ 35x = 910

⇒ x = 910 ÷ 35

⇒ x = 26

Answer:

(3x5) -6 = 3x3

Step-by-step explanation:

So we know that elijah starts with 3 sets of 5 marbles each.

This can be thought of as 3 x each set, or 3 x 5.

Elijah then gives away 6 marbles from this set, or in other words subtracts 6.

How can this be put into a equation, however?

We know that we are taking 3x5, and subtracting it by 6. However it isnt as simple as 3x5-6.

It would have to be (3x5)-6, since your sets are a total of 15, or 3x5. This total is being subtracted to by 6.

This can be written as:

(3x5)-6

The only equation in your list that looks like this would be the third one, where:

(3x5)-6 = 3x3

So this would be your answer!

Answer:

36? I believe im right

Step-by-step explanation:

Twice the difference of a number and four:  2(x - 4)

three times the sum of the number and 2:  3(x + 2)

2(x - 4) = 3(x + 2)

2x - 8 = 3x + 6

-14 = x

to confirm

2[(-14) -4] = 2(-18) =-36

3 [(-14) +2] = 3 (-12) = -36

Answer:

-4, 9, -1

Step-by-step explanation:

x³ - 4x² - 41x - 36

= x²(x + 4) - 8x² - 41x - 36

= x²(x + 4) - 8x(x + 4) - 9x - 36

= x²(x + 4) - 8x(x + 4) - 9(x + 4)

= (x + 4)(x² - 8x - 9)

= (x + 4) (x - 9)(x + 1)

so the zeros of f(x) are: -4, 9, -1

The required value of the given sum is given as 4.8. Option B is correct.

Given that,
To estimate the sum of 3.62 + 1.16 by rounding each addend to the nearest tenth.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
Given expression,
= 3.62 + 1.16
Round the values to the nearest tenth,
= 3.6 + 1.2
= 4.8

Thus, the required value of the given sum is given as 4.8. Option B is correct.

Answer:

  $12.80

Step-by-step explanation:

You are asked to estimate the tip by rounding the bill amount. The tip is the product of the (rounded) bill amount and the tip rate.

  rounded bill = $64.00

  tip rate = 20% = 0.20

  estimated tip = 0.20 × $64.00 = $12.80

Answer:

Step-by-step explanation:

We know that angles BAD and DAE are supplementary, so the measure of angle DAE is 180-133=47 degrees.

Because of this, we can determine that angle ADE measures 180-82-47=51 degrees.

Now, since triangles ADE and BCE are similar, we can say that the measure of angle ABC is 47 degrees and the measure of angle BCE is 51 degrees.

Finally, to find the measure of angle ADC, we can notice that its the supplement of angle ADE, meaning ADC measures 180-51=129 degrees.

Answer:

Inconsistent

4x + 2y = 6   and   4y = -8x + 4

Step-by-step explanation:

Inconsistent: parallel lines, no solutions

Consistent dependent: same line, infinite solutions

Consistent independent: intersects at one point, one solution

Therefore, the pair of lines are INCONSISTENT.

Both lines have negative slopes.  As they are parallel, the slopes will be the same for both lines.

Therefore, solution is:

4x + 2y = 6   and   4y = -8x + 4

Because:

4x + 2y = 6  ⇒  y = -2x + 3

4y = -8x + 4  ⇒  y = -2x + 1

Both lines have same slope of -2

Answer: 122 sq. ft.

Step-by-step explanation: First is a have to multiply 13 x 8 to find the area of the rectangle. Next, you have to find the area of the right triangles by multiplying 3 x 3 which would give you the area of two of the right triangles. Multiply 3x3 by 2 to find the area of all four right triangles combined. Finally, add 3 x 3 x 2 (18 sq. ft), to 13 x 8 (104 sq. ft). 18 + 104 = 122 sq. ft.

______

   8

multiply by 8 to both sides

x8          x8

2.8 + 2x = 4.8

subtract 2.8 from both sides

-2.8        -2.8

2x = 2

divide by 2 from both sides

/2      /2

x = 1

Answer:

x = 1

Step-by-step explanation:

Step 1: Multiply both sides by 8.

Step 2: Subtract 2.8 from both sides.

Step 3: Divide both sides by 2.

Therefore, x = 1.

Considering that it has an angle of 90º degrees, the triangle is classified as:

B. right

In this problem, two angles are 40º and 50º. Since the sum of the angles is of 180º, we have that:

x + 50 + 40 = 180

x = 90º.

Hence, it is a right triangle, and option B is correct.

Answer:

l = 81

w = 27

Step-by-step explanation:

l = 3x (x2)

w = x (x2)

l = 6x (has two sides so we x2)

w = 2x

6x + 2x = 8x

8x = 216

x = 27 (divide both sides)

w = 27

l = 27 x 3 = 81 (length is 3x bigger than width)

81 + 81 + 27 + 27 = 216

Answer:

Ric is 7 years old.

Step-by-step explanation:

Choose variables for everyone's ages. I'll choose [tex]r[/tex] for Ric's age, [tex]p[/tex] for Paul's age, and [tex]t[/tex] for Tom's age.

Since Ric's age is half of Paul's age, we can write this equation:

[tex]r=\frac{1}{2}p[/tex]

Since Tom is two years younger than Paul, we can write this equation:

[tex]t=p-2[/tex]

Since the sum of all their ages is 33 years, we can write this equation:

[tex]r+p+t=33[/tex]

Since we know [tex]t[/tex] and [tex]r[/tex] in terms of [tex]p[/tex], we can replace them in the equation above as follows:

[tex]r+p+t=33\\(\frac{1}{2}p)+p+(p-2)=33[/tex]

Now we can solve for [tex]p[/tex] to find [tex]r[/tex] later:

[tex](\frac{1}{2}p)+p+(p-2)=33\\\frac{5}{2}p-2=33\\\frac{5}{2}p=35\\5p=70\\p=14[/tex]

Now that we know that [tex]p=14[/tex], we can substitute 14 for [tex]p\\[/tex] in the equation[tex]r=\frac{1}{2}p[/tex]:

[tex]r=\frac{1}{2}p\\r=\frac{1}{2}(14)\\r=7[/tex]

Ric is 7 years old.
