You can use the fact that equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.
The equivalent equation to [tex]x + 4 = 64[/tex] is [tex]x = 60[/tex]
What are equivalent equations?Equivalent equations are such that one equation can be obtained by performing some operations(which doesn't break equality) on the other equation and vice versa.
How to get the equivalent equation of the given equation?The given equation is
[tex]x + 4 = 64[/tex]
Subtracting 4 from both sides, we get
[tex]x + 4 - 4 = 64 - 4\\x = 60[/tex]
Thus, one equivalent equation to the given equation is [tex]x = 60[/tex]
The equivalent equation to [tex]x + 4 = 64[/tex] is [tex]x = 60[/tex]

The perimeter of a basketball court is 90 meters and the
length is 6 meters longer than twice the width. What are the
length and width?
a
What is the width?
m
What is the length?
m
Answer:
w = 13 m
l = 32
Step-by-step explanation:
let 'w' = width
let '2w+6' = length
P = 2l + 2w
90 = 2(2w+6) + 2w
90 = 4w + 12 + 2w
90 = 6w + 12
78 = 6w
w = 13
length = 2(13) + 6 → 32
l = 32
check:
2(13) + 2(32) should equal 90
26 + 64 = 90
90 = 90 checks out

Jackson is two times older than Shelly if the sum of their ages is 18 how old is Jackson
Answer:
jackson is 12
Step-by-step explanation:
let the age be represented by x
jackson is 2 times older than shelly so
2x is jackson’s age and x is shelly’s age
since the sum of their ages is 18 then:
2x + x = 18
solve:
3x = 18 ➔ divide by 3 on both sides
x = 6
so now we know shelly is 6
jackson is 2 times older than her so:
2(6) = 12
hope this hello and hope it is right
Answer:
12
Step-by-step explanation:
since we know that Jackson is 2x Shelly - we can use trial and error.
for instance,
let's suppose Shelly is 6; that means that Jackson must be 12 (6 x 2)
we can check this answer by adding the two;
12 + 6 = 18
therefore, Jackson is 12
how to calculate sample size with standard deviation
Answer:
Step 1: Calculate the mean of the data—this is \muμmu in the formula.
Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations.
Step 3: Square each deviation to make it positive.
Step 4: Add the squared deviations together.
Step 5: Divide the sum by the number of data points in the population. The result is called the variance.
Step 6: Take the square root of the variance to get the standard deviation

mike has 5 2/3 pounds of sugar. he used 2 4/5 pounds of sugar to make cakes how many pounds of sugar dose he left
Answer:
[tex]2\frac{13}{15}[/tex]
Step-by-step explanation:
Given the following question:
[tex]5\frac{2}{3} -2\frac{4}{5}[/tex]
In order to find the answer to the question we have to subtract the initial amount of sugar by the amount of sugar Mike has left over after baking the cakes.
[tex]5\frac{2}{3}-2\frac{4}{5}[/tex]
To subtract fractions, we have to convert the mixed numbers into improper fractions and then find the least common denominator (LCD) to solve.
[tex]5\frac{2}{3} =3\times5=15+2=\frac{17}{3}[/tex]
[tex]2\frac{4}{5} =5\times2=10+4=\frac{14}{5}[/tex]
[tex]\frac{17}{3} -\frac{14}{5}[/tex]
Find the least common multiple:
[tex]LCD=15[/tex]
[tex]17\times5=85[/tex]
[tex]3\times5=15[/tex]
[tex]14\times3=42[/tex]
[tex]5\times3=15[/tex]
[tex]\frac{85}{15} -\frac{42}{15}[/tex]
Subtract the numerators:
[tex]85-42=43=\frac{43}{15}[/tex]
Convert into mixed number:
[tex]\frac{43}{15} =43\div15=2\frac{13}{15}[/tex]
[tex]=2\frac{13}{15}[/tex]

On Thursday, Mandy receives m messages. she doesn’t have time to read them,
so she splits the reading equally between her friends Candy, Sandy, Randy, and
Andy. Each of the four friends reads 43 messages. How many messages did
Mandy receive? Hint: Use a DIVISION equation!
Hi!
Let's start with the facts:
She had m messagesThey divided m messages into 4 equal groupsEach of those groups had 43 messagesWe must solve using a division equationTherefore:
[tex]\frac{m}{4}=43[/tex]
Now, we have an algebraic equation. In order to solve, we must multiply both sides by 4 so that way m is by itself.
[tex]\frac{m}{4}*4=43*4[/tex]
[tex]m=172[/tex]
Therefore, Mandy received 172 messages. (that's a lot of messages!)
