B. 7.5
C. 10.8
D 12.4
Answer:
7.5
Step-by-step explanation:
0.2(6r-5) =8 Distribute.
0.2(6r)-0.2 (5) =8 Simplify.
1.2r−1 =8 Add 1 to each side.
1.2r =9 Divide each side by 1.2.
1.2r/1.2 =9/1.2 Simplify.
r =7.5
Hope this helps!
Answer: Method of finding the sum of 46 and 7 is mentioned in below explanation.
Step-by-step explanation:
According to the question, we have to find out 46+7
First, we need to add 6 and 7 by that we get the result 13.
Where, 3 will be the digit in once place of our answer.
And, we need to add 1 in 4, that is 5 by that we get the tenth place digit of our result. which is 5.
So, our complete answer is 53.
4t + 3j = 181 and t + 2j = 94 represents the system of equations that can be used to represent this situation
Solution:
Let "t" be the cost of each t - shirt
Let "j" be the cost of each pair of jean
At a sale, Salazar bought 4 T-shirts and 3 pairs of jeans for $181
Therefore, we can frame a equation as:
4 T-shirts x cost of each t - shirt + 3 pairs of jeans x cost of each pair of jean = 181
At the same store, Jenna bought 1 T-shirt and 2 pairs of jeans for $94
Therefore, we can frame a equation as:
1 T-shirts x cost of each t - shirt + 2 pairs of jeans x cost of each pair of jean = 94
Thus eqn 1 and eqn 2 represents the system of equations that can be used to represent this situation
