6+4x. You multiply two times three and then multiply two times 2X
Distributive property: 3x3 and 3xn
So... 9x3n which becomes
27n
Answer:
-11x + 7y = 20
Step-by-step explanation:
See image. Multiply
2(-2x + 2y = 16)
You get -4x + 4y = 32
Then line that guy up underneath the
-15x + 3y = -12. You're adding vertically from the top down, x's with x's and y's with y's and plain numbers with plain numbers. See image
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
The answer is 9. 7 times 9 is 63 and then 63 divided by 3 is 9.
