Answer:
210 ÷7 = 30
Step-by-step explanation:
We can round the numbers to numbers that make the math easier
I will round 208 to 210
We know 21 divide by 7 is 3
210 ÷7 = 30
This is very close to the actual answer.
208÷7 = 29.71428571........
X = 180 - 150 = 30°
z = 180 - 100 = 80°
y = 180 - 30 - 80 = 70°
Answer: x = 30, y = 70, z = 80
Answer:
$2000
Step-by-step explanation:
let x be the money she invested
lets assume this was for 1 year
0.09(x/2) + 0.07(x/2) = 160
multiply each side by 2 to cancel the denominators:
0.09x + 0.07x = 320
0.16x = 320
x = 2000
The answer too this question is 4
Combined in mathematics is to add together to find a total. If you combine 1 and 2 you get 3.
