You would multiply 50 by ten to get 500 pennies.
Answer:
D. 296.00 LBS
Step-by-step explanation:
We convert both heights to inches.
1 ft = 12 in.
5 ft 3 in = 5 × 12 in. + 3 in. = 63 in.
6 ft = 6 × 12 in. = 72 in.
Answer: D. 296.00 LBS
2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)
Answer: 2x + 14y + 15
Step-by-step explanation:
8x - 6x + 10y + 6 + 4y + 9
Bring like terms together
8x - 6x + 10y + 4y + 6 + 9
Combine like terms
2x + 14y + 15
Hope this helped!
Answer:
I will answer in a general way because the options are not given.
We know that the area of model A is smaller than the area of model B.
For model A, we have 72 shaded sections, out of 100.
Then the quotient of model A is:
72/100 = 0.72
For model B we have 10 sections, and x shaded ones.
Because model B is greater than model A, we know that:
x/10 should be larger than 72/100
then we have the inequality:
x/10 > 0.72
x > 0.72*10
x > 7.2
And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:
10 ≥ x > 7.2
Then x can be any whole number in that interval.
the possible values of x are:
x = 8
x = 9
x = 10
