8 x 4 = ( y x 7 ) - ( y x 3 ) What is y?

Mathematics
1 answer:
ASHA 777 [7]2 years ago
4 0
8x4=32
32=(yx7)-(yx3)
(yx7)=7y
(yx3)=3y
32=7y-3y
7y and 3y are like terms so you subtract them
=4y
32=4y
then divided 4y by 4 (to get y on its own) this cancels out if you ÷ 4y on one side of the equation you have to divide on the other side to make it balanced 32÷4=8
y=8

How do i solve tis in need help <br> slope=2/7 y-intercept=-4
Thepotemich [5.8K]

Answer:

y=2/7x-4

Step-by-step explanation:

Write in Slope intercept form

y=mx+b

m = slope

b = y intercept

x = x intercept

y = (0,-4)

So,

y = 2/7x+(-4)   substitute

y = 2/7x-4

tia_tia [17]

Answer:

A=34, G=31

Step-by-step explanation:

G=A-3

2G+A=99

plug in for g 2(A-3)+A=99

distribute 2 A-3+A=99

combine like terms 3A-3=99

solve for a 3A=102 A=34

plug in a solve for g G=34-3 G=31

Janelle is in charge of bringing in dry erase markers for everyone in her math group to use to work on a project. She brings 3 m
Papessa [141]
Let x represent the number of students in Janelle’s group.  If  Janelle brings 3 markers for each person in her group, then she brings 3x markers for x students. You also know that she brings <span>5 extra markers for everyone to share. Thus, the total amount of markers she brings is 3x+5.
</span>
If Janelle brings in 23 markers in all, then the equation <span><span>3x+5=23 </span> represaents the mathematical model. </span>

3x=23-5,3x=18,x=6

Answer: there are 6 students in Janelle's group.

what are the solution(s) to the quadratic equation 9x2 = 4? x = 4/9 and x = -4/9 x = 4/9 and x = -2/3 x = 3/2 and x = -3/2 no re
Kamila [148]
To solve for the quadratic equation 9x² = 4, we need to recall that the difference between two square can be expressed as the product of their sum and difference or (a² - b²) = (a + b)(a - b). Thus, we have 9x² = 4 9x² - 4 = 0 (3x)² - (2)² = 0 (3x + 2)(3x - 2) = 0 We now have two linear equations: 3x + 2 = 0 | 3x - 2 = 0 3x = -2 | 3x = 2 x = -2/3 | x = 2/3 Thus, x = +2/3 and -2/3.<span> </span>
