<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations
-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>
The answer is 170 hope this helps this is the answer b to your Slove
Yep! :) You got it.
The answer is 46.
To find equivalent expressions,
distribute the first one and
factor the second one.
The SAT and ACT <span>generally test the same types of content. Both test scores are used for college admissions and merit-based scholarships. The biggest differences between the tests are that the ACT has a Science Test, and there’s one SAT Math Section for which you cannot use a calculator.

The best way to decide if the SAT or ACT is right for you is to take a timed full-length practice test <span>in each. Since the content and style of the SAT and ACT are very similar, factors like how you handle time pressure and what types of questions you find most challenging can help you determine which test is a better fit. For example, the pace of the SAT gives you a tad more time to think through problems, while the ACT can be more of a time crunch. Some students really thrive under the pressure of the clock, while others prefer the extra time to ponder a question.</span>
