Answer:
C: 3.0
Step-by-step explanation:
You can write a ratio as a fraction (12/4). Write it as a fraction then just do the math.
12/4 = 3
Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
<u>10x- 9 = 9x</u>
Subtract 9x from each side: x - 9 = 0
Add 9 to each side: <u> x = 9</u>
Now that we know what 'x' is, we can find the size of Angles-5 and -7 .
Angle-7 = 9x = 81° .
Now look at Angle-6 ... the one that's the answer to the problem.
Angle-6 and -7 together make a straight line, so they must
add up to 180°.
<u>Angle-6 + 81° = 180°</u>
Subtract 81° from each side: Angle-6 = <em>99° .</em>
Answer:
1. 5 cups of yellow paint.

Step-by-step explanation:
sorry if 4 is wrong
Answer:
-5
Step-by-step explanation:
The initial value would be the value when x=0. Substituting 0 for x,
y = -2(0)-5
y = 0 - 5
y = -5
Answer:
3/8 pounds of meat
Step-by-step explanation:
7/8 pounds of ham
= 0.875 pounds of ham
1 3/8 pounds of turkey
= 11/8 pounds of turkey
= 1.375 pounds of turkey
Pounds of meat
P_meat = 0.875 pounds of ham + 1.375 pounds of turkey
P_meat = 2.25 pounds of meat
Jon puts 1/6 of the meat on each sandwich
P_meat/6 = 3/8 pounds = 0.375 pounds
