Answer:
7 = 24
Step-by-step explanation:
Answer:
-14x +21 = 7x -24
Step-by-step explanation:
We assume your use of the multiplication symbol in this problem (×) is intended to represent the variable x.
The distributive property tells you that the factor outside parentheses multiplies each of the terms inside parentheses:
a(b+c) = ab+ac
Your equation can be simplified as ...
-7(2x -4) -7 = 3(x -5) +4x -9 . . . . given
-7(2x) +(-7)(-4) -7 = 3x +3(-5) +4x -9 . . . . use the distributive property
-14x +28 -7 = 3x -15 +4x -9 . . . . . . . . . . . carry out the multiplication
-14x +21 = x(3+4) -(15 +9) . . . . identify and group like terms on the right*
-14x +21 = 7x -24 . . . . . . . . . . do the arithmetic
_____
* note that the distributive property can also be used to combine terms:
3x +4x = x(3+4) = 7x
Answer:
t = 350
Step-by-step explanation:

Answer:
a. 22.5953 b. 3.6
Step-by-step explanation:
A. When a number is in parentheses and directly beside another number it means multiple. so you simply multiply to two together.
B. When a number is in parentheses but has a division sign or forward slash in front of it it is simply keeping the number separate as not to create confusion so just divide them.
ps. when you teacher says shoe work he/she means dint just write an answer. They mean write out beside your answer "2.43 x 9.71 = 22.5953" & "4.68 ÷ 1.3 = 3.6"
