Answer:
Nina sold 24 Amazebars Plz Mark Brainliest
Step-by-step explanation:
Cost:
80 x 0.40 = 32
180x 0.30 = 54
40 x 0 = 0
Total = 86
Income
80 x 2.25 = 180
180 x 2.25 = 405
X x 2.25 = 2.25x
Total = 585 + 2.25x
How many did she sell:
553 = 585 - 86 + 2.25x
553 = 499 + 2.25x
553 - 499 = 2.25x
54 = 2.25x
54/2.25 = x
24 = x
88 feet in 2 seconds
how many feet in 1 minute?
1 minute is 60 seconds
so, we can write a proportion and solve
feet/ seconds = feet/seconds
88/2 = x / 60
cross multiply
(88 * 60 ) = 2 * x
5280 = 2x
divide both sides by 2
2640 = x
To check:
88/2 =?= 2640 / 60
44 = 44
So the car travels 2640 feet in 60 seconds, or 1 minute.
(btw just in case you wanted to know also, 2640 feet is equal to 0.5 of a mile, that car travels 0.5 miles in 1 minute)
Hope this helps
Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
You can cross multiply on this and then solve.
140 / 60 = 200 / x
140x = 12000
x= <span>85.7142857143
x= 85.7</span>
Answer:
x = 136
Step-by-step explanation:
This one is quite simple
The shape formed inside of the circle is a quadrilateral.
when a quadrilateral is formed inside of a circle opposite angles of the quadrilateral will add up to 180
we are given x's opposite angle so we can find x by subtracting the given angle's measure (44) from 180
so x = 180 - 44
180 - 44 = 136
hence, x = 136
