What operation would isolate the variable -11 + m = 26

Answer:

48

Step-by-step explanation:

We must first find what is 75% of 64 (x), in order to find what this number is 120% of (y).

To find percentages, we can use the formula[tex]\frac{is}{of}=\frac{p percent}{100}[/tex], and we cross multiply and divide to find either the is value, of value, or the percent.

Thus, we have[tex]\frac{x}{64}=\frac{75}{100}\\ \\ 100x=(64*75)\\\\\frac{(100x=(64*75))}{100} \\\\x=48[/tex]

Now we want to find what 48 is 120% of:

[tex]\frac{48}{y}=\frac{120}{100} \\\\ 120y=(48*100)\\\\[/tex]

[tex]\frac{(120y=(48*100)}{120} \\\\y=40[/tex]

Answer:

40%

Step-by-step explanation:

Total amount is 15

6 out of the 15 amount are apples

Thus, 6/15 x 100 = 40%

Or

You could ask yourself, what number do I multiply by 15 to get to 100?

Then, multiply the top (numerator) by it.

The value of the numerator will give you the final % (percentage) due to percentage being out of 100.

Hope this helps!

Answer:

17

Step-by-step explanation:

17*5=85

4(17+2)=76

Answer:

the number= 17

Step-by-step explanation:

4 (x +2) = 5x -9

4x + 8 = 5x - 9

5x - 4x = 8 + 9

x= 17

Answer: x=1, y=1, z=-1

Step-by-step explanation:

From the first and 3rd equation, 2x+9y=11.

The first equation is also 4x+16y-4z=24, so add that to the second equation, and you get 6x+27y=33.

Solving, we get x=1 and y=1, meaning that z=-1.

Using confidence interval concepts, it is found that the interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.

It is given by the sample proportion plus/minus the margin of error, and a x% confidence interval means that we are x% sure the population proportion is in the interval.

134 of 420 randomly chosen likely voters indicated that they planned to vote for the Democratic candidate, hence:

p = 134/420 = 0.319

The margin of error for the statistic is 0.045, hence:

0.319 - 0.045 = 0.274

0.319 + 0.045 = 0.364

The interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.

Answer: 171/4, and 14.25

Step-by-step explanation:

We can solve this by first finding the area of each piece of fabric. Area is width multiplied by height, so:

3 * (4+3/4) = 57/4

We can multiply our answer by 3 again to find the total area.

57/4 * 3 = 171/4

To find the fabric as a decimal, we can first put it as a mixed fraction

[tex]14\frac{1}{4}[/tex]

This becomes 14.25

Answer: A

Step-by-step explanation:

C lies below g(x) and f(x), so we need [tex]f(x) \leq 3x+4[/tex] and [tex]g(x) \leq -\frac{1}{2}x-5[/tex].

D.No, because the total earned is $1255.70 per month.

Step-by-step explanation:

Essentially if your cost is 1543 a month, you simply wouldn't be able to afford it.

If you plug in 7.25 and 40 (you get 290) . With this information we plug it into weeks. In a month there are approximately 4.345 weeks (you can just times 290 by

4.34) which gives the stated result in the answer choice.

Step-by-step explanation:

A) [tex]-x+2y < -4[/tex]

[tex]-x+2y-2y < -4-2y[/tex]

[tex]-x < -4-2y[/tex]

Multiply both sides by -1 and reverse the inequality:

[tex]\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)[/tex]

[tex]x > 4+2y[/tex]

Answer:

[tex]x=\sqrt{40}, y=\sqrt{104}[/tex]

Step-by-step explanation:

Note the triangle formed by x, y, and 8 is similar to the largest triangle

so x : c = 8 : y = y : 13, where c is the rightmost vertical length, c² = x² + 5²

From 8 : y = y : 13, we get
y² = 13*8 = 104, so

[tex]y=\sqrt{104}[/tex]

From x : c = 8 : y, we have xy = 8c

x²y² = 64c²

104x² = 64(25 + x²)

104x² = 1600 + 64x²

40x² = 1600

x² = 40

[tex]x=\sqrt{40}[/tex]

The equation that's been computed shows that the number of cell phones that his family can have will be 2.

From the question, it was stated that the cell phone company charges $50 plus $40 per line each month and that Luke must spend under $170 on his family's cell phone bill each month.

Let the number of cell phones that can be bought be represented by x.

The equation to solve the question will be:

50 + 40(x) < 170

50 + 40x < 170

Collect like terms

40x < 170 - 50

40x < 120

x < 120/40

x < 3

Therefore, the number of cell phones has to be less than 3. Hence, this will be 2.
