Answer:
12x=10(25+x)
Step-by-step explanation:
Jim's rate=x
Pete's rate=y
Jim and Pete lays the same number of tiles.
So we have,
12x=10y
Pete's can lay 25 more tiles than Jim per hour
We have
y=25+x
Substitute y=25+x into 12x=10y
12x=10y
12x=10(25+x)
12x=250+10x
12x-10x=250
2x=250
x=250/2
=125
x=125
12x=10(25+x) is the equation used to find the rate that Jim can lay tiles

Step-by-step explanation:
Answer:
Both D and E are true statements.
Step-by-step explanation:
When you have the base form of slope-intercept form:
y = mx + b
The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.
The b is the intercept. In this case it would be -6
Since it’s in the tenths place it’s 50
Answer:
111 grams
Step-by-step explanation:
fruit: yoghurt: total
2 : 3 : 2+3=5
The total mass is 185
Divide 185/5 = 37
Multiply each number by 37
fruit: yoghurt: total
2*37 : 3 *37 : 5*37
74 111 185
The mass of the yoghurt is 111
