Answer:
D, E
Step-by-step explanation:
(4x - 1) ^2 = 11 => (take square roots of both sides)
4x - 1 = +\- sqrt(11) => (Add 1 to both sides)
4x - 1 + 1 = 1 +\-sqrt(11) =>
4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)
x = ( 1 +\- sqrt(11) ) /4
Which are choices D and E
Answer:
$110
Step-by-step explanation:
1. The total cost:
<em>(3 * 65) + (2 * 70) + (1 * 55)</em> -> cost of dresses + jeans + earrings
Total: 195 + 140 + 55 = <em>390</em>.
2. Money leftover:
<em>500 - 390</em> = $110.
Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.
Step-by-step explanation: <em>Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.
</em>
<em>
</em>
<em>Then divide the total number of cookies by the number of guests: 84 21 = 4. Each person would get 4 cookies.</em>
<em>
</em>
<em>This process can be modeled by the expressions 28(3) ÷ 21 and </em>
<em>28(3)
</em>
<em>21
</em>
<em>. This is because the fraction bar represents division.</em>
If you can find one leg of a triangle to be congruent to a leg on the other triangle, then you can use the HL (hypotenuse leg) theorem. If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Answer:
$54
Step-by-step explanation:
An expression for the total cost would be:
1($32) + ($32-$10) = $32 + $22 = $54
