Answer: B. 1.85 + x = 5.30
Explanation:
The starting height of the tree was 1.85 meters. To find the number of meters the tree grew, you would subtract the current height from the previous height.
5.30-1.85=x. This equation is the same as 1.85 + x = 5.30 if you switch the 5.30 and x.
So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
Answer:
That is true.
Step-by-step explanation:
A supplementary angle equals 180 degrees and and a right angle is 90, so 90+90=180
Answer:
The first equation answer is 10
And the second one 6
Step-by-step explanation:
The first equation
2/5 x +3= 2/3x +1/3
2x + 15/5 = 6x+3/9 the cress cross
9(2x + 15) = 5(6x + 3)
18x + 135 = 30x +15
135-15 = 30x - 18x
120 = 12x
120/12 =12x/12
10 = x
X =10
The second one
-2.6b +4 =0.9b - 17
-2.6b - 0.9b = - 17 - 4
-2.6b + (-0.9b) = - 17 + (-4)
-3.5b = - 21
-3.5b/-3.5 = - 21 /-3.5
B= 6
