Answer:
There are 25 males and 21 females in the class
Step-by-step explanation:
Let us use the equation to solve the question
∵ A Spanish class has a total of 46 students
∵ The number of males is 4 more than the number of females
→ Assume that the number of females is x
∵ The number of females = x
∴ The number of males = x + 4
→ Add the numbers of males and females and equate the sum by 46
∴ x + x + 4 = 46
→ Add the like terms in the left side
∴ 2x + 4 = 46
→ Subtract 4 from both sides
∴ 2x + 4 - 4 = 46 - 4
∴ 2x = 42
→ Divide both sides by 2
∴
∴ x = 21
∵ x represents the number of females
∴ There are 21 females
∵ x + 4 represents the number of males
∴ The number of males = 21 + 4 = 25
∴ There are 25 males
Answer:
B. 3(y-5)/2. Once it's multiplied it equals 3y/2 - 15/2
Step-by-step explanation:
Pedro did KCF (Keychain flip)
Step 1&2 are correct as he did the process right.
So, he must of multiplied or simplified wrong
So, 4×8= 32
And 7×8=56
As you may have noticed he has gotten 20/50 instead of 32/56
Where Pedro messed up is step 3
HOPE THIS HELPER (:!
make the decimal into into 3
then
3/10×3 =9/10=0.9
Refer to image...the y intercept is 8 which means y is 8 when x is 0, then you go down one from there (down to the right)
