Answer:
a. 3x = 45
15cm
Step-by-step explanation:
Given the perimeter of an equilateral triangle = 45cm .
Using the equation
3x = 45
Divide both sides by 3
x = 45/3
= 15cm
The length of each side of the triangle is 15cm because an equilateral triangle has its three sides equal
Your answer is A. (0,0)
The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept, which is where the line cuts the y-axis.
In the line y = 4x, the ‘m’ would be 4 and the ‘+ b’ would be 0, which means that the line cuts the y-axis when y = 0.
There are only 2 answer options that have y = 0, A (0, 0) and D (4, 0). To find out which is correct, we can substitute in y = 0 into the equation y = 4x to see what the x-value would be:
y = 4x
0 = 4x
0 = x
Therefore the answer is A.

10 * (1.025)^9 = 12,48
Maybe 12.49 depending on rounding.
Answer: he saved $15
Step-by-step explanation:
The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is
8.5/2 = $4.25
If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is
20 × 4.25 = $85
The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is
5 × 20 = $100
Therefore, the amount saved by the bushes on sale is
100 - 85 = $15
