Answer:u
Step-by-step explanation:
V/4-15=29
Multiply each term by 4
V - 60 = 116
V = 116 + 60
V = 176
(-1) 3x + 2y = 10.45
4x + 3y = 14.30
---------------------
x + y = 3.85
x = 1.55
y = 2.90
Answer: John has 52 marbles in his collection
Step-by-step explanation:
Step 1
LET The number of marbles in John's collection can be represented by x. The and the number of marbles in Erica collection can be represented as =4x+ 10
The total number of marbles in both collections is 270 such that the expression to solve the equation will be
JOHN + ERICA = 270marbles
X + 4X+ 10= 270
Step 2--- solving
X + 4X+ 10= 270
5X+ 10= 270
5X= 270-10
5X= 260
X= 260/5
=52
John has 52 marbles in his collection
Erica has 4x + 10 = 4x 52 + 10=218 marbles
