3x + 1 = y
2x + 3y = 14
To solve this system of equations, we are going to use the substitution method. Substitution the equation where the variable is isolated into the second equation. In this system of equations, y is isolated, so we will replace y in the second equation with 3x + 1.
2x + 3y = 14
2x + 3(3x + 1) = 14
2x + 9x + 3 = 14
We will add the like terms and subtract 3 from both sides of the equation.
11x + 3 = 14
11x = 11
x = 1
In this system of equations, x is equal to 1. Now we will go back and solve for y, plugging in 1 for x.
3(1) + 1 = y
2(1) + 3y = 14
3 + 1 = y
2 + 3y = 14
4 = y
3y = 2
4 = y
4 = y
The solution to this system of equations is (1, 4).
Answer: That is false.
Step-by-step explanation: You have 43 chromosomes, but during reproduction, you use only half of those and your partner uses the other half to make a baby.
2 hours. She spent 1 hour for math which was half so the total would be 2*1=2.
1/2x=1 /x2
x=2
Answer:
SOLVE FOR RECTANGLE
Area: lw (length times width)
rectangle: lw (6x6)
AREA=36in
SOLVE FOR TRIANGLE B
Area: A=hbxb/2
A=hb/b2=6·6/2=18
TRIANGLE B=18in
SOLVE FOR TRIANGLE A
Area: A=hbxb/2
The height looks half the height as the other triangle
A=hb/b2=3·4/2=6
TRIANGLE A=6in
{ADD}
36+18+6
TOTAL: 60in
