Answer:
infinitely many solutions
Step-by-step explanation:
-8T- 20 = 4(-2T -5)
Distribute the 4
-8T- 20 = (-8T -20)
Add 8T to each side
-8T+8T- 20 = (-8T+8T -20)
-20 = -20
Since this is a true statement, there are infinitely many solutions
Answer:
7.5 flour bag
Step-by-step explanation:
we are given
flour bags need to make 1 dozen cookies=3/4
we have to find
number of flour bags for 10 dozen cookies needed =?
1 dozen cookies needed flour=3/4
and for 10 dozen cookies
we will multiply 10 on both sides
it will give
10 dozen cookies needed flour bags=(3/4)*10=30/4=15/2=7.5
Answer:
Step-by-step explanation:
equation (1):
equation (2): y=2x
solve the system by substitution
step1: sub (2x) for y in equation 1:
step2: simplify the expression:
(divide by 2 for both sides)
To find the value for y sub 21/4 for x in equation 2:
y=2x
y=2×(21/4)
3 is your answer.
