Answer:
<u>The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75</u>
Step-by-step explanation:
1. Let's check all the information given for solving this question:
Cost of bag of chips = US$ 1.25
Cost of sandwich = x
Cost of total order = US$ 38.75
2. The formula for find the cost of sandwich (x) is this:
5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)
5x = 37.50 (Subtracting 1.25 at both sides)
5x/5 = 37.50/5 (Dividing by 5 at both sides)
x = 7.50
<u>The cost of each sandwich was US$ 7.50</u>
A^2 - b^2 = (a - b)( a +b);
<span>cos^4x-sin^4x =( cos^2x + sin^2x )( cos^2x - sin^2x) = 1* cos2x = co2x.</span>
It would be c I did all the calculations for it
Answer:
Step-by-step explanation:
let the integers be x,x+1,x+2
x+x+1+x+2≤951
3x≤951-3
3x≤948
x≤316
greatest value of x=316
x+1=316+1=317
x+2=316+2=318
so integers are 316,317,318
Greatest inter=318
Answer:
x=2
Step-by-step explanation:
y=-7x+13
y=-1
plug in -1 for y in the first problem.
-1=-7x+13
subtract 13 by both sides
-14=-7x
divide both sides by -7 to isolate x
2=x
hope that helped have a good day
