3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5
So that is why your welcome
You have 6 choices for where to place the H, 5 choices for the A, 4 choices for the E, and 3 choices for the R
(and then the 2 T's go in the remaining places).
This gives 6⋅5⋅4⋅3=360 choices.
Answer:
y /< 5/2 x +5
Step-by-step explanation:
y is less than or equal to 5/2 x plus 5
since its a solid line and shaded below you would use less than or equal to
The cost is $395. You are trying to find <em>n</em> in 24<em>n</em> + 35.
Set C = 395.
You get 395 = 24<em>n</em> + 35.
Solve for <em>n</em> by first subtracting 35 from both sides of the equation:
395 - 35 = 360.
24<em>n</em> + 35 - 35 = 24<em>n</em>.
Now you have 360 = 24<em>n</em>. Divide both sides by 24 to get:
15 = <em>n</em>.
So, 15 birthday cakes are made when the cost is $395.
