Mathematics
1 answer:
andriy [413]3 years ago
6 0

Answer:

B

Step-by-step explanation:

∠ ABC = 9x + 5 ( alternate angles )

∠ ABC and ∠ DCB are sam- side interior angles and sum to 180° , that is

9x + 5 + 16x = 180

25x + 5 = 180 ( subtract 5 from both sides )

25x = 175 ( divide both sides by 25 )

x = 7

Then

∠ ABC = 9x + 5 = 9(7) + 5 = 63 + 5 = 68° → B

Guy wants to swim 500 meters. After 75 meters, he takes a break. What percent of his goal has he already met?
iren2701 [21]
To determine this, we need to set up proportions.
x/100 = 75/500.
A quick way to find x, the percentage we're looking for, is to cross multiply our fractions.
100 x 75 and 500 with x.
75 x100 = 7500, and 500 times x is 500x.
7500=500x
Divide by 500 on each side.
15 = x
Your answer is C.)15%.
I hope this helps!

Solve the system of equations. y= x + 17, y= 3x+1
Lemur [1.5K]

Answer:

x=8, y=25. As a point it's (8,25)

Step-by-step explanation:

here is the system:

y=x+17

y=3x+1

notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)

so it'll be:

3x+1=x+17

subtract 1 from both sides

3x=x+16

subtract x from both sides

2x=16

divide by 2

x=8

now, substitute 8 as x into one of the equations and solve for y

let's take the first one for example

y=8+17

y=25

so the answer is x=8, y=25. As a point it's (8,25)

Hope this helps!
