Answer: x=8

Step-by-step explanation: Since we know that segment AB and BC are the same measure indicated by the black lines running perpendicular to the lines in triangle themselves, we know that angle A and angle C are the same measure. This means we know this equation... Solve this to complete step 1...

69°=(9y-3)°

If you solve for y, you should get 8. This means that y=8. In knowing that a triangle's interior angles add up to 180°, we know that Angle B must be... Solve this equation for step 2...

∠B=180°-(∠A+∠C)

If you solve to find angle B, you should get that ∠B=42°. Knowing this, we can set up another equation similar to that in step 1 (when we found y knowing the angle) to find x... Solve this equation for your third and final step...

42°=(5x+2)°

If done step 1 through 3 correctly, you should get x to be equal to... and the final answer... x=8

there are four Defenders on a soccer team that this represents 20% of the players on the team which equation can be used to find

gladu [14]

4=(total players on the team) x 0.2
(total players on the team) = 4/0.2
(total players on the team) = 20
****
20% is the same as 0.2.
2 is 20% of 10.
to find 10, divide 2 by 0.2
2/0.2=10
4 is 20% of something
to find 'something', divide 4 by 0.2
4/0.2=20

Maria calls her mother 5 times every week. Let w represent the number of weeks and c represent the total number of times Maria c

galina1969 [7]

Answer:

Equation: 5w = c

Step-by-step explanation:

${ \tt{w \: \alpha \: c}} \\ { \tt{w = kc}}$

k is a constant of proprtionality

${ \tt{1 = (k \times 5)}} \\ { \tt{k = \frac{1}{5} }}$

» Therefore, equation becomes:

${ \tt{w = \frac{1}{5}c }} \\ \\ { \boxed{ \tt{5w = c}}}$

Which statement describes the relationships between x and y in these two equations?

Maru [420]

B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.

Out of all the answer choices, b makes the most sense.

25x can be translated as 25 times x.

x + 25 can be translated as 25 more than a number.

Hope this helps!
