8 tables will be in each row because 8 times 8 would be 64
Answer:
Equation: 7x + 8x = 180
x = 12
∠CBA = 84
∠CFH = 96
Step-by-step explanation:
We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.
We know that the sums of two angles on a straight line are going to be equal to 180.
∠CBA = 7x
∠CFH = 8x
To find the value of x, we must do the following:
7x + 8x = 180
15x = 180
15x/15 = 180/15
x = 12
Now we just substitute to find the angle measures:
∠CBA = 7 · 12 = 84
∠ CFH = 8 · 12 = 96
Answer:
200 minutes
Step-by-step explanation:
Given that:
Cellular - Tastic (f) :
Monthly fee = $35
Per minute fee = $0.11
Dirt cheap call (g) :
Monthly fee = $55
Per minute fee = $0.01
How many minutes would you need to use for the cell phones to cost the same
amount?
Let number of minutes for cost to be equal = x
35 + 0.11x = 55 + 0.01x
Collect like terms
0.11x - 0.01x = 55 - 35
0.1x = 20
x = 20/0.1
x = 200
Hence, for cost to be the Same, 200 minutes must be used
6/x= -2/18
Cross multiply. ( Multiply the numerators together ) . ( Multiply the denominators together (.
6*18= - 2*x
108= -2x
Divide by -2 for 108 and -2x
108/-2= -2x/2
x= -54
Answer: x= -54
5/6 litre of Smoothie = 2/3 cups of smoothie
Divide both sides by 5/6
So 1 litre of smoothie = 2/3 ÷ 5/6 cup of smoothies
= 2/3 × 6/5 cup of smoothies
= 4/5 cup of smoothies
