10 + 2x – 4 = 2x + 1 + x ?
Answer:
x = 5
Step-by-step explanation:
10 + 2x - 4 = 2x + 1 + x
First, we can subtract 2x from both sides:
10 - 4 = 1 + x
We can simplify 10-4 to 6:
6 = 1 + x
Now, we can subtract 1 from both sides:
5 = x
x = 5
Answer:
x=5
Step-by-step explanation:
10+2x=4=2x+1+x (Then subtract 2x from both sides)
-2x. -2x
10-4=1+x (Simplify)
1+x=10-4 (Switch sides)
1+x=6 (Then subtract the numbers: 10-4=6)
1+x=6 (Subtract 1 from both sides)
-1 -1

Farmer John walks his pet pig around his barn every day. The barn is 25
meters by 12 meters. If we walks the pig around the barn three times, how
many meters did farmer John and his plg walk?
Answer:
900m
Step-by-step explanation:
A=wl
W=25
L=12
A=25 x 12
A= 300
300 meters x 3 laps = 900 meters walked
Farmer John and his pig walks 222 meters distance if he walks the pig around the barn three times.
What is rectangle?A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.
Give that,
The length of Barn = 25 meters.
And width of Barn = 12 meters.
The perimeter of barn = 2 (12 + 25) = 2 x 37 = 74 meters.
Since, farmer walks the pig around the barn 3 times,
So the total distance covered by farmer John and his pig
= 3 x perimeter of barn
= 3 x 74
= 222 meters.
Hence, farmer and his dong covers 222 meters distance.

DS=3x+10 and SE=6x-2. What is the value of DE?
Answer:
9x+8
Step-by-step explanation:
Given DS = 3x+10 and SE = 6x-2_ the value of DE is expressed as shown;
DE = DS+SE
Substitute the given functions into the formula to get DE
DE = (3x+10)+(6x-2)
Open the parentheses
DE = 3x+10+6x-2
Collect the like terms
DE = 3x+6x+10-2
DE = 9x+8
Hence the value of DE is 9x+8

What is the slope of the line with the coordinates (0,0) and (-4,7).
Answer:
Slope = -7/4
Step-by-step explanation:
Let's find the slope between your two points.
(0,0) ; (−4,7)
(x1,y1) = (0,0)
(x2,y2) = (−4,7)
Use the slope formula:
m = y2−y1 / x2−x1
= 7−0/−4−0
=7/−4
= −7/4
Answer:
m= −7/4

one number is 2 less than a second number. twice the second number is 22 more than 5 times the first
Answer:
The first number is -6. The second number is -4.
Step-by-step explanation:
Let the second number be x.
"one number is 2 less than a second number"
Second number: x
First number: x - 2
"twice the second number is 22 more than 5 times the first"
2x = 5(x - 2) + 22
Distribute on the right side.
2x = 5x - 10 + 22
Subtract 5x from both sides. Combine like terms on the right side.
-3x = 12
Divide both sides by -3.
x = -4
x - 2 = -4 - 2 = -6
The first number is -6. The second number is -4.

When is a quadrilateral both a trapezoid and a parallelogram? Complete the explanation.
When there are (select: no pairs, one pair, two pairs) of parallel lines, which are lines with (select: the same slope, different slopes)
Answer:
TWO PARALLEL LINES AND LINES WITH EQUAL LENGTHS
Step-by-step explanation:
As we all know a quadrilateral is a polygon with four sides(edges and corners). Trapezoid is a four-sided shape with opposite sides parallel while parallelogram is also a for sided shape that has its opposite sides paralleled.
NOW, a quadrilateral is said to be both a trapezoid and a parallelogram when there are two opposite parallel lines, which are lines with equal lengths.

2. Write 1.68 as a simplified fraction
a. Write an expression that represents the total cost of large pizza. let t = # of toppings.
b. Brust orders an “everything” pizza with 8 toppings. use your expression to find the total cost of the pizza.
c. Kelly and Bean show up and order 4 identical pizzas. write an expression that represents the total cost for the 4 pizzas. (each pizza would have the same # of toppings.)
d. Kelly and Bean order sardines and pineapple on the 4 pizzas. use your expression from (c) to find the total cost of the 4 pizzas.
Answer:
a). Total cost of one pizza = 14.99 + 1.99t
b). $30.91
c). Cost of 4 pizza = 59.96 + 7.96t
d). Total cost of 4 pizza with 2 toppings = $75.88
Step-by-step explanation:
a). Cost of the large pizza = $14.99
Each topping of the pizza is $1.99 extra.
If total number of layers of the toppings = t
Total cost of one pizza = 14.99 + 1.99t
b). Brust orders a pizza with number of toppings = 8
From the given expression,
Total cost of pizza = 14.99 + 1.99(8)
= 14.99 + 15.92
= $30.91
c). Kelly and Bean ordered number of identical pizzas = 4
Expression that represents the cost of 4 pizzas = 4(14.99 + 1.99t)
= 59.96 + 7.96t
d). Kelly and Bean order 4 pizzas with sardines and pineapple. That means 2 toppings on one pizza.
Cost of 4 pizza with toppings = 59.96 + 7.96×2
= $75.88

the letters a and b represent nonzero constants. solve ax+b=12.5 for x. x=12.5/a
Answer:
[tex]x=\frac{12.5-b}{a}[/tex]
Step-by-step explanation:
[tex]ax+b=12.5\\\\ax+b-b=12.5-b\\\\ax=12.5-b\\\\\frac{1}{a}*ax =\frac{1}{a}*(12.5-b)\\\\x=\frac{12.5-b}{a}[/tex]
The value of x is x=(12.5-b)/a
What is equation?An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.
For example, 3y = 16 is an equation.
Given equation:
ax+b=12.5
Now,
ax= 12.5-b
x=(12.5-b)/a

Which statement must be true.
The sum of 9 and the quotient of x and 7 is 11
Answer:
Expression: 9 + x/7=11
x=14
Step-by-step explanation:
The expression would 9 + x/7=11 because it says the sum of 9 and the quotient of x and 7. Quotient means the answer to a division problem, and sum means the answer to an addition problem.
x=14 because when you subtract 9 from both sides of the equation, you will get x/7=2
Then, 7*2=14, so that is why x=14
