If a = 3 and b = 2, what is the value of the expression 11 + a - b ?

1 answer:

4 0

Substitute the values of a and b into the expression:
11 + 3 - 2
Add first because of order of operations (perform addition and subtraction in the order of occurrence from left to right):
14 - 2
Subtract (same justification as above just with subtraction instead):
12
Hope this helps!

Last year Rikki sang 960 songs with his rock band. How many songs did he sing per month? How did you get your answer?

If he sang the same number of songs each month, he sang 80 songs per month.

960/12 (months) = 80 (songs per month)

Answer:

Step-by-step explanation:

For 11 1/2 gallons, he paid $36.80.

We need to find the cost per gallon.

First, converting 11 1/2 gallons to decimal, it is:

1/2 = 0.5

So, 11 1/2 is 11.5 gallons

So, Cost Per Gallon (last week) = $\frac{36.80}{11.5}=3.2$

There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.

5% = 5/100 = 0.05

0.05 * 3.20 = 0.16

So,

3.20 + 0.16 = $3.36 per gallon

Cost Per Gallon (this week) = $3.36

To buy 9 1/4 gallons it would take:

$3.36*9.25=31.08$

Note: 1/4 = 0.25, so 9 1/4 = 9.25

It would cost $31.08 to buy 9.25 gallons this week

Correct answer is B

Brainliest, what is the total measure of angles 8 and 5 of angle 7 equals 61

guapka [62]

Lines equal 180°. The line with angles 5 and 7 equals 180°. If angle 7 equals 61°, then angle 5 equals 119° (180° - 61°= 119°).

Angles 5 and 8 are opposite vertical angles, which are always congruent (equal), so angles 5 and 8 both equal 119°.

119° (angle 5) + 119° (angle 8)= 238°

ANSWER: The two angles total 238° (bottom choice).

Hope this helps! :)
