Answer:

No solution

Step-by-step explanation:

Substitution method:

(Since y values are defined, make them equal to each other)

y = 152 + 9

y= 22 – 20

152 + 9 = 22 -20

161 ≠ 2

I need help thanks so much

Answer:

c. 1 $\frac{3}{8}$ inches

Step-by-step explanation:

Since the paper clip is past the 1, the answer will be 1 and ___.

the mark in the middle of the 1 and 2 is one half (1/2)

the mark in between the 1 and 1/2 is 1/4

the mark between 1/4 and 1/2 is 1/8

there are three (3) 1/8 marks where the paperclip is

3 * 1/8 = 3/8

so your answer is 1 3/8

hope this helps:)

Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

$m =\frac{y_2 - y_1}{x_2 - x_1}$

Pick any two corresponding points from the table

So, we have:

$(x_1,y_1) = (8,1.21)$

$(x_2,y_2) = (12,1.63)$

So:

$m =\frac{y_2 - y_1}{x_2 - x_1}$

$m =\frac{1.63 - 1.21}{12 - 8}$

$m =\frac{0.42}{4}$

$m =0.105$

The linear equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y = 0.105 * (x - 8) + 1.21$

Open bracket

$y = 0.105x - 0.84 + 1.21$

$y = 0.105x + 0.37$

To get the length closest to 4.2lb,

we set $y = 4.2$

Then solve for x

So, we have:

$y = 0.105x + 0.37$

$4.2 = 0.105x + 0.37$

Collect like terms

$0.105x= 4.2 - 0.37$

$0.105x= 3.83$

Solve for x

$x= 3.83/0.105$

$x\approx 36.5$

you have three fifths of a pie you divide the remaining pie into 5 equal slices what fraction of the original Post in each slice

Savatey [412]

So you divide $\frac{3}{5}$ by 5:
$\frac{3}{5}$ ÷ $\frac{5}{1}$ which is:
$\frac{3}{5}$ × $\frac{1}{5}$ = $\frac{3}{25}$

So your answer is: $\frac{3}{25}$

B-8. This is because -4 to 0 is 4 and then 0-4 is 4. 4+4=8

Solve for x then, find m < FDG and m <GOF.

Marat540 [252]

Answer:

choice 4) x = 27, ∠FDG = 62°, ∠GOF = 118°

Step-by-step explanation:

2x + 8 + 4x + 10 = 180°

6x + 18 = 180

6x = 162

x = 27

∠FDG = 2(27) + 8 = 62°

∠GOF = 4(27) + 10 = 118°
