Answer:
70
Step-by-step explanation:
1) "20% of a number is 56"
Lets call this number "x".
0.20x = 56 (percents can become decimals by dividing 100)
2) 45% of the same number is 126
This will be the same number "x".
0.45x = 126
3) Divide by 0.45 (you can use a calculator)
0.45x / .45 = 126 / .45
x = 280
4) "25% of that number"
that number is x
25% is one-fourth of a number so
0.25x = 280/4
0.25x = 70
This equation simplified is 2-3x

Answer:
Two triangles are congruent if their corresponding sides are equal in length and their corresponding interior angles are equal in measure. We use the symbol ≅ to show congruence. Corresponding sides and angles mean that the side on one triangle and the side on the other triangle, in the same position, match.Step-by-step explanation:
The value of the expression is -24
This is because you distribute the -4 to both of the values in the parenthesis like this:
-4(7) + -4(-1)
This can be simplified to:
-28 + 4
Which equals -24
Hope this helps!
