Answer:
1) The trick to making these fractions equivalent is to make sure they have the same denominator. to do this you need to know your multiplication facts. These are the multiples when you multiply two numbers together.
2) Since 24 is the largest denominator, you need the smallest denominator into 24ths, which you do by multiplying 8 x 3, giving you 24.
3) Whatever you do to the denominator, you do to the numerator, so multiply 5 x 3, which is 15.
4) New fraction for 5/8 becomes 15/24.
5) So 5/8 is equivalent. to 15/24.
Step-by-step explanation:
5/8 = x/24
5 x 3 = 15
8 x 3 24
Proof: Reduce 15/24 by dividing 3 into both numbers (15÷3) and (24÷3) = 5/8.

Question 2
Evaluate the following function:
f(x) = 7x2 + 8x + 20 for f(2)
type the numerical value for your answer
Answer:
64
Step-by-step explanation:
We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.
Since we know that x equals 2. We can substitute 2 for every x in the expression.
7(2)^2 + 8(2) + 20
First do the exponent :
2^2
4
7(4) + 8(2) + 20
Multiply 7(4) and 8(2) :
7(4)
28
8(2)
16
28 + 16 + 20

The points (1,1) and (5,5) fall on a particular line. What is its equation in slope- intercept form
Answer:
y=x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-1)/(5-1)=4/4=1
slope is 1
y-y1=m(x-x1) where m=slope
y-1=1(x-1)
y-1=x-1
y=x-1+1
y=x
Answer:
y = x

4 Eric sketches a rectangle with a perimeter of
90 inches. The length of the rectangle is three
inches longer than the width. Which equation
can be used to determine x, the width of the
rectangle Eric sketched?
F 2x + 2x + 3 = 90
G 2(x + 3) = 90
H x(x + 3) = 90
J 2(x) + 2(x + 3) = 90
Answer:
2(x) + 2(x + 3) = 90
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2 [tex]w^{}[/tex] + 2 [tex]l^{}[/tex]
P = 2(x) + 2(x + 3) = 90

Marion is driving between two towns that are close together. If she drives 1/5 the distance of the trip in 15 minutes, what is her rate per hour?
Answer: 75 minutes per hour.
Step-by-step explanation:
From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.
The rate per hour will then be:
= 15 ÷ 1/5
= 15 × 5
= 75 minutes
The rate per hour will then be 75 minutes per hour.

Answer: 42
Step-by-step explanation:
whats her errors and whats the soulution
Answer:
she messed up at -17=34x
Step-by-step explanation:
she added 8x to each side but she was actually supposed to subtract
The error is 8(x - 3) + 7 = 2x(13) and -17 = 34x.
4 - 17 = -13, not 13
8x - 17 = 26x
-17 = 26x -8
-17 = 18x ( it should be like this, but this is still wrong because it should -26)
The solution is:
8(x - 3) + 7 = 2x(4 - 17)
8(x - 3) + 7 = 2x(-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
8x + 26x = 17
34x = 17
x = 17/34
x = 1/2

(1) One apple weighs 75 grams and one orange weighs 40 grams. The weight of x apples and y oranges, is
Answer:
Given,
Weight of each apple =75 gm
Weight of each orange =40 gm
So,
Weight of x apples =75x gm
Weight of y oranges =40y gm

At the end of the summer, I decide to drain the swimming pool
(which has 1500 gallons of water in it). I noticed that it drains
faster when there is more water in the pool. That was interesting
to me, so I decided to measure the rate at which it drains. I found
that it was draining at a rate of 1% every minute.
How long will it take to empty the pool?

Hola alguien puede ayudarme a resolver estos ejercicios por favor Ejercicios de intervalos 1.- Escribe en todas las formas posibles los siguientes intervalos y semirrectas: a) { x / –2 ≤ x < 3} b) Números mayores que –1 c) (–[infinity], –5] d) Números mayores o iguales que –7 y menores que 19. e) Números mayores que 9 y menores que 5.
Answer:
Tenemos 3 formas de escribir cada intervalo, una es con solo texto, la otra es usando los símbolos { <, >, ≤, ≥ }, y la última es con intervalos, donde:
( se usa para " < x "
) se usa para " > x "
[ se usa para " ≤ x "
] se usa para " ≥ x "
a) -2 ≤ x ≤3
Esto se escribe como:
"números mayores o iguales que -2 y menores o iguales que 3"
y
[-2, 3]
b) Números mayores que –1
Las otras formas de escribir esto son:
-1 < x
y no tenemos limite mayor, entonces:
(-1, ∞)
con -∞ y ∞ siempre se usan los símbolos ( o )
c) (–[infinity], –5]
Las otras notaciones son:
"Un numero menor o igual que -5"
x ≤ -5
d) Números mayores o iguales que –7 y menores que 19
Las otras notaciones son:
-7 ≤ x < 19
[-7, 19)
e) Números mayores que 9 y menores que 5.
Las otras formas de escribir esto son:
5 < x < 9
(5, 9)
