Answer:
1. About 9 left. 2. £21 left
Step-by-step explanation:
First, you do 65 ÷ 3 = 21.7 if rounding to the tenths, 21.67 if to the hundredths, and so on. Then you do 21.67 - 12 = 9.67. But since it is cards, I would say about 9 left.
First you add the £20 to the £70 to get £90. then you multiply 7×3 to get £21 spent on books. After that, multiply 12×4 to get £48 spent on games. then do 48 + 21 = 69. 90-69= 21.
Here is the equation....
(70+20)-[(7×3)+(12×4)] = £21
Answer:
She sold 39 tall candies and 52 short candies
Step-by-step explanation:
x is all the tall candies
y is all the short candies
x+y=91
8x+5y=572
Use the method of Substitution to find out both x and y.
x=91-y
8(91-y)+5y=572
728-8y+5y=572
728-3y=572
3y=156
y=52
x+52=91
x=39
L=2W-4
PERIMETER=2L+2W
58=2(2W-4)+2W
58=4W-8+2W
58=6W-8
6W=58+8
6W=66
W=66/6
W=11 ANS. FOR THE WIDTH.
L=2*11-4
L=22-4
L=18 ANS. FOR THE LENGTH.
PROOF:
58=2*18=2*11
58=36+22
58=58
Answer:
<h2>
</h2>
Step-by-step explanation:
f(x) = 2x + 4
g(x) = 4x² + 1
In order to find (g ∘ f)(0) we must first find
(g ° f )(x)
To find (g ° f )(x) substitute f(x) into g(x) that's for every x in g(x) replace it with f(x)
That's
<h3>
</h3>
We have
<h3>
</h3>
Now to find (g ∘ f)(0) substitute the value of x that's 0 into (g ∘ f)(0)
We have
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
I think its C) bc you would take 3.14 x4= 12.56
