C) 3
Step-by-step explanation:
Because she paid 6.50, you subtract that by 5 and it will get you 1.50 and then you divide that by .50 and it gets you your answer.
Answer: angle 1=129 degrees
Step-by-step explanation:
180 - 99 - 30 = 51
all the angles of a triangle should add up to be 180 degrees
51+99+30=180
angle 1 is supplementary to the angle that is 51 degrees so it would be 129 degrees. 180-51=129
Answer:
hi
Step-by-step explanation:
4- 3*1=3
6*1/100= 0.06
3+0.06= 3.06
5- 7*1= 7
3*1/10= 0.3
4*1/1,000= 0.004
7+0.3+0.004= 7.304
7- 3.3, 3.30
8- 9.3000, 9.30
9- 9.6, 9.600
10- 4.4000, 4.40
for #4-5 just put the number of 0s in the denominator of the fraction for the answer
The value of a is 
Step-by-step explanation:
<u>1. Determine the other solution of x</u>
If one value is 5 + 
then the other value is 5 -
<u>2. Use reverse technique to find the equation</u>
(5 + ) (5 - ) = 0
25 - 
+ 
- 
= 0
- + 25 = 0
<u>3. The equation is</u> - + 25 = 0
<u>4. Find the value of a</u>
a is the number with the variable 
therefore it is -

If you think about it, 4x7 is half of 8x7 (If you multiply 4, 7, and 2, you get 8x7). So really you can just multiply 4x7 by 2 and you will get 8x7!
