Michael is shopping for clothes. He needs to buy an equal number of shirts and fies. He also needs to buy 4 times as many shirts as pants. Shirts cost $35, ties cost $25, and pants cost $40. If Michael spends S560, how many shirts did he buy?

Michael bought 8 shirts

Step-by-step explanation:

Let the number of shirts to be buy be x

The number of ties too will also be x

The number of pants will be x/4 since he will be buying four times the number of pants for shirts

Amount spent on shirt is 35 * x = $35x

Amount spent on ties = 25 * x = $25x

Amount spent on pants = 40 * x/4 = $10x

Adding all together;

35x + 25x + 10x = 560

70x = 560

x = 560/70

x = 8

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
