you are making curtains by alternating strips of solid colored fabric and patterned fabric. the solid colored fabric costs 99¢ p
weeeeeb [17]
Hello, 

to find the total cost (c) of the colored strips we have to multiply the number of strips (n) by the cost of each color strip (99¢), that as an algebraic function is:

\boxed{c= n*99} [¢]

Now, if we use 3 solid color strips, that means that we use 4 patterned strips, so:

Cost=3*0.99+4*1.25 \\ \boxed{Cost= 7.97}

Answer: c=n*99   and   Cost per curtain= $7.97

7 more than 5 times a number is 122
Luba_88 [7]

Answer:

The number is 23.

Step-by-step explanation:

5n + 7 = 122               Subtract 7 on both sides

     5n = 115                 Isolate the variable by dividing 5 on both sides

        n = 23

PLZ HELP SCALE FACTOR TRIANGLE<br><br> A. 10.5 cm<br> B. 31.5 cm<br> C. 63 cm<br> D. 189 cm
Anarel [89]

If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².

We have the ratio:

54:18=\dfrac{54}{18}=3:1

Area of the smaler triangle = x

Area of the larger triangle = 567 cm²

Therefore we have the equation:

567:x=3^2:1^2\\\\\dfrac{567}{x}=\dfrac{9}{1}\qquad|\text{cross multiply}\\\\9x=567\qquad|\text{divide both sides by 9}\\\\x=63

<h3>Answer: C. 63 cm²</h3>
