So we know that there are 8 slices per large pizza (7), so a total of 56 slices
we would set up a proportion
5/8=x/56
8 times 7 gives you 56, and we would do that same thing to the 5 (multiply it by 7) to get 35?
so now we know that 35 out of 56 slices were eaten
56-35 is 21
so there are 21 slices left over
Answer:
x = -5
y = 4
Step-by-step explanation:
3x + 4y = 1 /*(-4)
4x + 5y = 0 /*3
---------------------
-12x - 16y = -4
12x + 15y = 0 +
---------------------
-y = -4
y = 4
---------------------
12x = -15y
12x = -60
x = -5
---------------------
Answer:
-6x +10x= 4x
Step-by-step explanation:
-2x(3 - 5x)
-6x +10x= 4x
Answer:
Arccos(0.9272) =0.383929333 radian
0.383929333 radian =(0.383929333*57.2957795)degrees
so, 21.99 degrees
Step-by-step explanation:
Rounding to the nearest we get 22 degrees
We know that,
1 radian is equal to 57.2957795
so we multiply the radian value 0.383929333 with it
Answer:
D 8√(10) ^3x
Step-by-step explanation:
We have
sqrt(10) ^ (3/4x)
We can rewrite the sqrt as ^1/2
10 ^ (1/2) ^ (3/4x)
We know that a^b^c = a^(b*c)
10 ^(1/2 *3/4x)
10 ^(3/8 x)
The numerator is the power
The denominator is the root
8√(10) ^3x
