Answer:
y=4*10-1
y=39
you just need to replace the x with 10
The value of y, when x=10 is 39.
The given equation is y = 4x - 1.
We need to find the value of an equation for x=10.
How to solve an equation?Solving equations is computing the value of the unknown variable still balancing the equation on both sides. An equation is a condition on a variable such that two expressions in the variable have equal value. The value of the variable for which the equation is satisfied is said to be the solution of the equation.
Now, put x=10 in the given equation and simplify.
That is, y=4×10-1
⇒y=39
Therefore, the value of y, when x=10 is 39.

Patricia has $12 to spend at an arcade. The arcade charges $6 admission and $3 per hour to play as many games as she wants. Which inequality can be used to find any possible number of hours, x, Patricia can play games without spending more than $12?
Answer:
The inequality is 6 + 3x ≤ 12 or x ≤ 2 .
Step-by-step explanation:
Given that $6 is for admission which is a fixed amount, $3 is charged per hour and must not spend more than $12. So the inequality will be :
Let x be the no. of hours,
6 + 3x ≤ 12
Solve :
6 + 3x ≤ 12
3x ≤ 12 - 6
3x ≤ 6
x ≤ 6 ÷ 3
x ≤ 2

Answer:
-43
Step-by-step explanation:
The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.
What is an expression?An algebraic expression consists of unknown variables, numbers and arithmetic operators.
Given are two expressions, (3m+2n-6) and (-4-6m+7n)
Putting m = 5 and n = -2, we get,
(3m+2n-6) = 3x5-2x2-6 = 15-4-6 = 15-10 = 5
(-4-6m+7n) = -4-6x5-7x2 = -4-30-14 = -30-18 = -48
(3m+2n-6) + (-4-6m+7n) = -48+5 = -43
Hence, The sum of the expression (3m+2n-6) and (-4-6m+7n) when m = 5 and n = -2 is -43.
