Yes because if you multiply 332 with 39 to get how much bricks you need, it will be 12,948. 15,000 is more than 12,948 so it is enough
Answer:
5:2
Step-by-step explanation:
5:2 represents for every 5cm it is converted to 2m
X+10+3x+18=180 is the first part
4x+28=180
4x=152
x=38
1) y=?x+4
2) y=?x+10
Use the formula y= mx+b to simply convert.
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
For two lines to be perpendicular, the slope of one line is the negative reciprocal of the other line. The equation of the given line is
y = 2x - 2
Comparing with the slope intercept form,
Slope, m = 2
This means that the slope of the line that is perpendicular to it is -1/2
The given points are (-3, 5)
To determine c,
We will substitute m = -1/2, y = 5 and x = - 3 into the equation, y = mx + c
It becomes
5 = -1/2 × - 3 + c
5 = - 3/2 + c
c = 5 + 3/2
c = 13/2
The equation becomes
y = -x/2 + 13/2
