Answer:
The minimum score is 28.
Step-by-step explanation:
(95+54+98+81+2x)/6>64
(328+2x)/6>64
328+2x>384
2x>384-328
2x>56
x>28
<span>√3 * 2√2 * 5√8 * 18
2 x 5 x 18
10 x 18
180
</span>√3 x √2 x √8 =
√6 x √8 =
√48
√48 = 6 x 8 = 3 x 2 x 2 x 2 x 2 = 4√3
180 x 4√3 = 720√3
720√3 should be your answer
hope this helps
Let cheese wafers = x
chocolate wafers = y
we know they bought 20 total packets so x+y = 20, this can be re-written as x = 20-y
cheese wafers cost 2, so we have 2x
chocolate wafers cost 1, so we have 1y, which is just the letter y
so we know 2x + y = $25
replace x with x=20-y to get:
2(20-y)+y = 25
distribute the parenthesis:
40-2y +y = 25
combine like to terms to get:
40-y = 25
subtract 40 from each side"
-y = -15
divide both sides by -1
y = 15
chocolate wafers was y so they bought 15 chocolate wafers
cheese wafers was x, so they bought 20-15 = 5 cheese wafers
using the substitution method was the easiest way to isolate one of the variables in order to find the solution.
-2(3x - 5)
Distributive property.
-6x + 10
<h3>The simplified binomial is -6x + 10.</h3>
