3 18 3 14
6 9
Answer:
a-b=10
Step-by-step explanation:
add all the numbers then round
13+ 14+ 22+ 52+ 63+ 77=241
Round to the nearest ten
a =240
first rounding each number to the nearest ten and then add
13+ 14+ 22+ 52+ 63+ 77
10+10+20+50+60+80 =230
b= 230
a-b = 240-230
= 10
Answer: -5/4
Step-by-step explanation:
Apply the fraction rule: a/-b = -a/b
-5/6/2/3
-----------------------------------------------------------------------------------------------------------------
Divide fractions: a/b/c/d = a x d/ b x c
-5 x 3 / 6 x 2
-----------------------------------------------------------------------------------------------------------------
Multiply the numbers: 6 x 2 = 12
-5 x 3 / 12
-----------------------------------------------------------------------------------------------------------------
Multiply the numbers: 5 x 3 = 15
-15/12
-----------------------------------------------------------------------------------------------------------------
Cancel the common factor.3
-5/4

Sorry if this is a little confusing but your answer to the question is ( -5/4 )
Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt Substitute
41 = r * 2.3 Divide by 2.3
41 / 2.3 = r Switch sides
r = 41/2.3
r = 17.83 mph Answer
Find the GCF of 80 and 32.
I'd start by identifying possible integer factors of both 80 and 32:
80: {1,2,4,5,8,10,16,20, 40, 80}
32: {1, 2,4, 8, 16, 32}
Working backwards, we see that the first factor that is represented in both lists is 16. Is 80 evenly divisible by 16? Yes; the quotient is 5.
Is 32 evenly divisible by 16? Yes; the quotient is 2.
You could writet 80 + 32 as 16(5 + 2). This is a product equal to 112, just as 80 + 32 = 112.
