Answer:
23
Step-by-step explanation:
If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.
This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.
f(4)=4*4+7
f(4)=16+7
f(4)=23
Answer:
y=15
Step-by-step explanation:
Because of the exterior angle theorem angle A plus angle b or equal to 146.
so you set 5y+3+4y+8=146 and solve
5y+3+4y+8=146
9y+11=146
9y=135
y=15
Answer:
¹²/₇
Step-by-step explanation:
Model ⁴/₇ × 3
Assume that you have three pies, each dived into seven slices.
There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate
The picture represents ⁴/₇ × 3.
Model the product
Now, transfer slices to get as many filled pie plates as possible.
Count the total slices.
You have 12 slices, and each slice represents ⅐ of a pie.
You have ¹²/₇ pie.
∴ ⁴/₇ × 3 = ¹²/₇
Answer:
Step-by-step explanation:
54 equals 9 more than a number
So if we do this, we get
54 = x+9
x+9 = 54
54-9=x
54-x = 9
A.; 14 doesn’t work and neither does 8 or 3.
