Roger has 2 1/2 cups of butter. A recipe for a loaf of bread requires 3/4 cup of butter. How many loaves can roger bake?
Alchen [17]

In order to calculate the number of loaves Roger can bake, we should calcculate how many times 3/4 (required butter for one loaf of bread) is included in 2 1/2 (amount of butter Roger has).

2 1/2=4/2+1/2=5/2

(5/2)/(3/4)=5*4/2*3=20/6=3,33

Roger can bake 3 loaves of bread.

What is the equation of a line that passes through the point (2, 7) and is perpendicular to the line whose equation is y=x/4+5 ?
worty [1.4K]

Answer:

y = -4x+15

Step-by-step explanation:

y=x/4+5 may be presented as y = 1/4 x + 5, where a=1/4, b=5

swapping numerator and denominator and inserting an opposite sign in a=1/4, we have:

1/4 --------> 4/1 -------> -4/1 = -4

y = -4x+n

Point (2,7) means that x=2, y=7 substitute it to the equation y=-4x+n, calculate "n":

7=-4*2+n ------>    7=-8+n ------->   7+8 = n -------> 15=n

substituting n=15 to the equation y=-4x+n, we get finally y=-4x+15

Solve systems of three variable equations - how to do :(​
krek1111 [17]

a= 6-2b-3c

then put that equation inside the first one and then the second one

you get -6*(6-2b-3c)+2b-3c=23

and 5*(6-2b-3c)+4b-3c=-12

14b-15c=59

14b-18c=18/*(-1)

--------------------

3b=41

For X, (3x-40°)=2x-10°)​
KATRIN_1 [288]

Hello!

3 x - 40^0 = 2 x - 10^0

3 x - 1 = 2 x - 1

3 x = 2x

3 x - 2 x = 0

Hence, the answer is 0

I hope this helps, and have a nice day!
