Answer:
x=9 :))
Step-by-step explanation:
First set up your equation.
"3 times" is multiplication
"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it
"is increased by ten" that is an addition at the end
Now we have 3(x+7)+10=4
Solve your equation!
Distribute the 3 now we have 3x+21+10=4
Add like terms
now it should look like this... 3x+31=4
Subtract 31 from both sides and it looks like...
3x=27
Divide by the x-value
x=9
Answer: 60°
Step-by-step explanation: use exterior angle property,
therefore, y+70°=130°
y=130°-70°
y=60°
Given :
Emilie rides her bike x miles before she gets a flat tire.
She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.
To Find :
Which expression shows how many miles Emilie travels in all.
Solution :
We know, total distance covered is given by sum of all the distance she travelled.
Distance covered, D = x + 1/3 + 2 1/2
D = x + 1/3 + 5/2
D = (6x + 2 + 15)/6
D = (6x + 17)/6
Therefore, total distance travelled by Emilie is (6x + 17)/6 .
Answer:
Distributive property
Step-by-step explanation:
The distributive property states a(b+c)=a*b+a*c. This property states that when you multiply more than one thing, you must be sure to multiply everything. When you order fast food combos, you do the distribution property to receive the correct order.
If I order 3 Happy Meals, then I will receive
3(hamburgers +fries + drinks +toys)
3 hamburgers+3 fries+3 drinks+3 toys.
If I don't, then I have broken the distribution property.
Answer:
-1 
Step-by-step explanation:
4x-8y=15
4x-8y-4x=15-4x
-8y=15-4x
-8y/-8=15-4x/-8
y=-1 7/8+1/2x
slope is -1 7/8
