Answer:
8
Step-by-step explanation:
4(x + 7) = 38
Since there is no operation sign between the 4 and parenthesis, it makes it an automatic multiplication problem.
You would use distributive property to multiply each which should leave your equation looking like this afterwards:
4x + 28 = 38
(4 times x and 4 times 7)
You would then solve it like a two step equation,
1. +28 - 28 = 0
2. 38 - 28 = 10
4x = 10
10 divided by 4 = 2.5
x = 2.5
We can recheck our work by substituting in the value of x.
4(2.5 + 7) = 38
10 + 28 = 38
When we substituted in the value, it gave us the correct inequality.
Therefore,
x = 2.5
ASA because when you look at the corners it marks the angles and then a line for the side in between it. That’s how I always looked at it
Answer:
43.75%
Step-by-step explanation:
answer:
423.5
step1.
you find the value of 3% by dividing over 100 because percentage is over 100 so 3/100
step2
multiply by $350
so 3/100×350=10.5
step3
we are told the investment is for 7years so we multiply 10.5 by 7 because 10.5 is only for 1year
10.5×7=73.5
step4
add the 73.5 to the 350 then you have your answer
