The point (7, 8) is the solution of which of the following systems of equations?
Alex73 [517]

Option 4

<u>V</u><u>e</u><u>r</u><u>i</u><u>f</u><u>i</u><u>c</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u>

\\ \sf\longmapsto x-7y=-49

\\ \sf\longmapsto 7-7(8)=-49

\\ \sf\longmapsto 7-56=-49

\\ \sf\longmapsto -49=-49

And

\\ \sf\longmapsto 10x+9y=142

\\ \sf\longmapsto 10(7)+9(8)=142

\\ \sf\longmapsto 70+72=142

\\ \sf\longmapsto 142+142

Hence verified

The sale price of a laptop is R3 700,00, which is only 65% of the original price. Calculate the original price.​
Mandarinka [93]

The original price of a laptop that is 65% of the sales price is R3 1076923.07692

<h3>How to find the original price when given the percentage?</h3>

The sale price of a laptop is R3 700,00,which is only 65% of the original price.

Therefore,

let

x = original price

Hence,

700, 000 = 65% of x

700,000 = 65 / 100 of x

cross multiply

70000000 = 65x

divide both sides by 65

x = 70000000 / 65

x = 1076923.07692

Therefore, the original price of the laptop is R3 1076923.07692
