To solve for j, cross multiply:
4 x 45 = 18 x j
180 = 18j
Divide both sides by 18:
j = 10
Answer:
<em>The sale price of the washing machine is £207.50.</em>
Step-by-step explanation:
<u>Percentages
</u>
To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.
Suppose the normal price of the washing machine was x before the discount. The discount is:
17% of x = 17/100 * x = 0.17x
This discount is given as £42.50, thus:
0.17x = £42.50
Solving:
x = £42.50/0.17
x = £250
The sale price is:
£250 - £42.50 = £207.50
The sale price of the washing machine is £207.50.
Answer:
Step-by-step explanation:
there is a linear relationship
from the table, x changes by +6, y changes by -3 every time
so that means the slope is constant i.e. its a straight line
slope=(y2-y1)/(x2-x1)=-3/6
= -1/2
take the 1st pt, ( 1, -4 )
(y-(-4)) = slop * (x-1)
y+4 = -1/2*(x-1)
ans is A
Answer:
d. 64
Step-by-step explanation:
x^2+16x
The coefficient of the x term is 16
Divide by 2
16/2 =8
Then square it
8^2 = 64
We add 64
x^2 +16x +64
(x+8)^2
