5x+2y=22. -2x+6y=3 What is the X coordinate of the solution. Round to the nearest tenth
just olya [345]
Multiply first example by 3 and subtract by second example, you will get the following:

3*(5x + 2y) = 3*22   =>  3*5x + 3*2y = 66      =>  15x + 6y = 66
now subtraction:
(15x + 6y) - (-2x + 6y) = 66 - 3
15x + 6y + 2x - 6y = 63
15x + 2x + 6y - 6y = 63
17x = 63
x = 63/17 ≈ 3.705..... and as it says to round to the nearest tenth our answer would be: x = 3.7

At Ralphs Italian Ices, 145 sundaes were sold in June. Sales were up 23% in July, How many sundaes were sold in July?​
elena-s [515]
178 sundaes were sold in July.

To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23

145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35

You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.
