my 5th grader answered it he needs some help with his math and we saw this question and he wanted to help. So if it's not right I'm sorry it was out of kindness
Mark has 18 and Don has 77 number of marble to sell.
Let’s say Mark has x number of marble and Don’s marble number is y.
According to this problem we have,
Y = 4x +5
And x + y = 95
Or, x + 4x + 5 = 95
Or, 5x = 90
Or, x = 18 and y = 77

Answer:
Step-by-step explanation:
Y-intercept is -2.
Using slope formula, 2-(-2)/2-0 = 4/2 = 2 = slope.
Plugging into slope-intercept form:
y=mx+b => y=2x-2
Answer:
The system of equations is given as:
x + y = 2.5 .... Equation 1
1.8x + 1.8y = 4.05....Equation 2
Step-by-step explanation:
Kiran says, "I bought 2.5 pounds of red and yellow lentils. Both were $1.80 per pound. I spent a total of $4.05
Let
x represent red lentils
y represent yellow lentils.
x + y = 2.5 .... Equation 1
x = 2.5 - y
$1.80 × x + $1.80 × y = $4.05
1.80x + 1.80y = 4.05....Equation 2
The system of equations is given as:
x + y = 2.5 .... Equation 1
1.8x + 1.8y = 4.05....Equation 2
