A food service in the mall prepares free samples of chicken to give out during dinner time. One hour later, the food service has
jeka94

The food service gave out 80 samples, which is 4 fewer than 70% of the total number of samples they prepared. Lets make x the total number of samples they prepared.

So lets write it as an equation

80 = (70% of x) -4

70% converts to a decimal by moving the decimal point 2 spaces up, so it is 0.7

80 = 0.7x-4

Add 4 to both sides of the equation

84 = 0.7x

Divide both sides by 0.7 to isolate the x

x = 120

The food service prepared 120 samples.

Whats the answer ???? help dude
Natali [406]

Answer:

C. 44 °

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

180 - 88 = 92

Angles in a triangle add up to 180 degrees.

y + y + 92 = 180

y + y = 88

2y = 88

y = 88/2

y = 44

scoray [572]

Answer:

B) Line EG and OM

Step-by-step explanation:

We already know that EF and ON are congruent as well as angle MON and GEF so that means that the only thing we need to know to make it SAS would be EG and OM because we already have the angle and with that length then we know that line FG will be congruent to NM. We would not want to compare NM and FG because then we would get AS* not SAS.
