17 - 4x = 33
What does X=?

Answers

Answer:

x = -4

Step-by-step explanation:

17 - 4x = 33

Subtract 17 from each side

17-17 - 4x = 33-17

-4x = 16

Divide each side by -4

-4x/-4 =16/-4

x = -4

Which expression is equivalent to - 2/3 (6x + 15) ?
A.
4x + 10
B.
4x – 10
C.
-4x - 10
D.
- 4x + 10

Answers

Answer:

-4x - 10

Step-by-step explanation:

Given the expression -2/3(6x+ 15)

Open the bracket

-2/3(6x+ 15)

= -2/3 (6x) -2/3(15)

= -2(2x) - 2(5)

= -4x - 10

hence the equivalent expression is -4x - 10

Percent error:

26/172*100% = 15% rounded to the whole number

Step-by-step explanation:

[tex]\% \: error = \frac{198 - 172}{172} \times 100 \\ = \frac{26}{172} \times 100 \\ = 15\%[/tex]

How to graph 2x + y = 4 ?
Explain steps please !!

Answers

you need to rearrange your equation to make y the subject which would be

y= -2x+4

this now matches the formula y= mx+c , -2 being m and 4 being c.

c is your y intercept so the graph will go through 4 on the y axis. Then m is the gradient of your graph and because it is negative you know it is going downwards. 2 means that every unit value you go across the x axis the y axis will go down 2.

To find where your graph crosses the x axis you need to make y=0 in your equation which looks like
0=-2x+4
2x=4
x=2

Now you know that your x intercept is 2 so you can draw a line going through 4 on the y axis and 2 on the x axis like my photo.

The highest recorded temperature in the world was at Azizia, Libya, on September 13, 1922. The temperature was 58.0°C. The lowest temperature, -88.3°C, was recorded at the Soviet Antarctic station Vostok on August 24, 1960. What is the difference in these two temperatures?

Answers

Answer:

the difference in these two temperatures is 146.3°C

Step-by-step explanation:

The computation of the difference in these two temperatures is as follows:

= Highest temperature - lowest temperature

= 58.0°C - (-88.3°C)

= 58.0°C + 88.3°C

= 146.3°C

Hence, the difference in these two temperatures is 146.3°C

It is determined by the applying the above formula and the same is relevant

Quinn likes to knit hats and mittens for friends and family. Last fall, she knitted 4 hats and 3 pairs of mittens, which took a total of 56 hours. This fall, she knitted 3 hats and 1 pair of mittens, which took a total of 27 hours. If each hat and each pair of mittens takes the same amount of time to knit, how long does it take Quinn to knit a hat and a pair of mittens?

Answers

Answer:

hats = 5

mittens = 12

Step-by-step explanation:

hats = h

mittens = m

Uknown:

- How many hours per hats

- How many hours per mittens

Known:

- How many hours in total

- How many pairs of mittens made

- How many pairs of hats made

4h + 3m = 56

3h + 1m = 27

3h + m = 27

m = -3h + 27

4h + 3m = 56

4h + 3(-3h + 27) = 56

4h - 9h + 81 = 56

-5h = 56 - 81

-5h = -25

-5h/5 = -25/5

-h = -5

-h/-1 = -5/-1

h = 5

3h + m = 27

3(5) + m = 27

15 + m = 27

m = 27 - 15

m = 12

Check: h = 5, m = 12

4h + 3m = 56

3h + 1m = 27

4h + 3m = 56

4(5) + 3(12) = 56

20 + 36 = 56

56 = 56

3h + 1m = 27

3(5) + (12) = 27

15 + 12 = 27

27 = 27

Answers

Answer:

c.

Step-by-step explanation:

when the fish swam down 55, you moved 55 to the left of zero. then when he swam 30 up, you take that 55 and move it 30 towards to the right. since -55 is greater than 30, your answer is still negative. -55+30=-25.

It’s an inequality I need the work for it ik the answer

Answers

Answer:

Solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

Step-by-step explanation:

We need to solve the inequality: [tex]1<\frac{a+7}{-2}[/tex]

We need to solve the inequality, to find the value of a.

Solving the inequality:

[tex]1<\frac{a+7}{-2}[/tex]

First step is Switching both sides (the inequality will be reversed)

[tex]\frac{a+7}{-2}>1[/tex]

The next step is to multiply both sides by -2 and reverse the inequality

[tex]\frac{a+7}{-2}*-2<1*-2\\a+7<-2[/tex]

Now, subtracting 7 on both sides

[tex]a+7-7<-2-7\\a<-9[/tex]

So, solving the inequality [tex]1<\frac{a+7}{-2}[/tex] we get the value of a: [tex]\mathbf{a<-9}[/tex]

XY zand ABC are similar. If angle X is 32 degrees and angle Y is 84
degrees, find the measure of angle C.

Answers

Answer:

B

Step-by-step explanation:

A triangle always has a degree total of 180. x+y=116 180-116=64 therefore the last angle, angle c, must be 64 degrees.

Answer: B. 64 degrees

Step-by-step explanation:

∠C = 180° - (∠X + ∠Y)

∠C = 180° - (32° + 84°) = 180° - 116° = 64°

In 1970, the median home value was $20,000. By 2020, the median home value was $320,000. What is the percent increase in home value in those 50 years?

Answers

Answer:

1500%

Step-by-step explanation:

The formula for Percentage increase is

Increase/ Initial Amount × 100

Increase = Current Amount - Initial Amount

Increase = $320,000 - $20,000

Increase = $300,000

Percentage Increase =

$300,000/$20,000 × 100

= 1500%

The percent increase in home value in those 50 years is 1500%
