Answers

Answer:

x = -4, y = 3

Step-by-step explanation:

In one equation (let's use the top one), solve for one of the variables (let's solve for y first).

5x - 2y = - 26 --> -2y = -5x - 26 --> y = (5/2)x + 13

Now, substitute ((5/2)x + 13) in for y in the second equation.

-7x + 4((5/2)x + 13) = 40 --> -7x + 10x + 52= 40 --> 3x = -12 --> x = -4

Then, subtitute that in to one of the equations.

5(-4) - 2y = -26 --> -20 - 2y = -26 --> -2y = -6 --> y = 3

x+2y-z = 9
-2x+y+z= 1
2x-y+2z= -5

The land John owns covers an area of 2.17 x 104 square miles. The land Sam owns covers an area of 5.34 x 103 square miles. About how many times greater is the area owned by John than the area owned by Sam?

Answers

Answer:4.064 times

Step-by-step explanation:

Step 1

Area  of  Land owned by John =2.17 x 104 square miles

Area  of  Land owned by Sam= 5.34 x 103 square miles.

When we say about how many times is a quantity greeter than the other we mean that  how much is the smaller quantity contained in the larger quantity. and in such cases, we divide.

Area  of  Land owned by John/Area  of  Land owned by Sam

=2.17 x 104 square miles/ 5.34 x 103 square miles

=21,700 square miles /5,340 square miles

=4.064 times

Therefore  we say that John's owns an area of land  by 4.064 times Sam's land.

Jose can use the rule m(x)=10+3x to find m(x) , the amount of money he will have after a week of doing x additional hours of chores. Evaluate m(20), What does this mean?

Answers

Answer:

70

Step-by-step explanation:

Given:

m(x) = 10 + 3x

where,

m(x) = the amount of money he will have after a week of doing x additional hours of chores

x = additional hours of chores

Evaluate m(20), What does this mean?

m(x) = 10 + 3x

m(20) = 10 + 3(20)

= 10 + 60

= 70

m(20) = 70

m(20) means additional hours of chores is 20

The equation of the line is y - 3 = 2.5(x - 2) ⇒ D

Step-by-step explanation:

The rule of the slope of a line is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

(x1, y1) and (x2, y2) are two points on the line

The point-slope form of a line is y - y1 = m(x - x1), where

(x1, y1) is a point on the line

From the given figure

∵ The line passes through points (2, 3) and (0, -2)

∴ x1 = 2 and y1 = 3

∴ x2 = 0 and y2 = -2

→ Substitute them in the rule of the slope to find it

∵ m = [tex]\frac{-2-3}{0-2}=\frac{-5}{-2}=2.5[/tex]

m = 2.5

→ Substitute the values of m, x1, y1 in the form of the equation above

∵ m = 2.5, x1 = 2, y1 = 3

y - 3 = 2.5(x - 2)

The equation of the line is y - 3 = 2.5(x - 2)

Claire wants to build a patio outside her café. The rectangular space outside of Claire's café is three times as long as it is wide. The area of the space is 48 m2. Claire
would like to build a patio with dimensions 3.5 m by 12.5 m in this space. Will it fit? Explain.

pls help​

Answers

Answer:

Step-by-step explanation:

It will fit in the space but it won't cover the entire space. the area is 48m2, but the patio in question will cover 43.75 of the 48m2. Also, it stated that the rectangular space is 3 times as long, and the patio is 3.57x as long as the width. So yes, it will fit, but it will not be a picture perfect fit, there will be some obscenities.

Step-by-step explanation:

Let length of space be lm and width be wm.

l = 3w --(1)

lw = 48 --(2)

sub (1) into (2):

3w(w) = 48

3w^2 = 48

w^2 = 16

w = ± 4 (rej -4 since w > 0)

when w = 4, l = 3(4) = 12

Since dimensions of the patio is 3.5m by 12.5m, and the dimensions of the space is 4m by 12m it does not fit

Marsha recorded the time it took seven children of different ages to run one lap around the track.
Using the line of best fit, which is closest to the length of time it should take Marsha's 6 year old niece to
run one lap?
A. 190
B. 200
C. 205
D. 210

Answers

The answer is C. 205.
Answer: C

Reasoning: There is a 40s difference between the age of 4 and 8 meaning 6 most likely would be in the center of that, which also means it’d be about half of 40. So with that we subtract 20 from 225 and thus giving us the closest length of time it should take Marsha’s 6 year old niece to run one lap, 205s.
