Answer:
a variable is an unknown number by the way the answer is 4 too.
3+x=7
-3 -3
______
x = 4
subtract 3 on both sides to get x (the variable) by itself.
Answer:
good morning here is your answer,
3+x=7

SOMEONE PLEASE ANSWER!!!!
Evaluate each expression for t = 0, x = 1.5, y = 6, and z = 23
1. y + 5 = ??
2. z - 2x = ??
3. 2z - 2y = ??
4. 2.6y - 2x =??
5. 4(y - x) = ??
6. 4(2 + z) + 5 = ??
Answer:
1. 11
2. 20
3. 34
4. 12.6
5. 18
6. 105
Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5
= 105
helpppp 2x-1>5 and 3x-5<19
Answer:
3 < x < 8
Step-by-step explanation:
Solve each part separately
2x - 1 > 5 ( add 1 to both sides )
2x > 6 ( divide both sides by 2 )
x > 3 , that is
3 < x
and
3x - 5 < 19 ( add 5 to both sides )
3x < 24 ( divide both sides by 3 )
x < 8
Then putting the two together
3 < x < 8

the equilateral triangle and the rectangle have the same perimeter.
triangle: 2.5x + 10. rectangle: x +12 + 8x
what is the value of x?
what is the perimeter of the rectangle?
Answer: x = - 4/13
Step-by-step explanation:
2.5x+10=x+12+8x
10-12 = x+8x-2.5x
-2 = 6.5x
x = -4/13

Calvin owns a toy store. He can spend at most $200 on restocking cars and dolls. A doll costs $6.50, and a car costs $8.00. Let x represent the number of cars, and let y represent the number of dolls. Identify an inequality for the number of toys he can buy. Then identify the number of dolls Calvin can buy if he buys 10 cars.
8x + 6.50y ≤ 200; no more than 19 dolls
8x + 6.50y ≤ 200; no more than 18 dolls
6.50x + 8y ≤ 200; no more than 19 dolls
6.50x + 8y ≤ 200; no more than 18 dolls
The required inequality expression is 8x + 6.50y ≤ 200
Maximum amount he can spend = $200
Cost of doll, = $6.50
Cost of car = $ 8.00
Mathematically, the maximum amount he can spend on restocking is cars and doll is :
(Cost of cars × number of cars) + (cost of doll × number of dolls) ≤ maximum amount
8x + 6.50y ≤ 200
Hence, the required inequality expression is : 8x + 6.50y ≤ 200

What is the Triangle Congruence Theorem and is it congruent?
Answer:
Two triangles are congruent if their corresponding sides are equal in length and their corresponding interior angles are equal in measure. We use the symbol ≅ to show congruence. Corresponding sides and angles mean that the side on one triangle and the side on the other triangle, in the same position, match.Step-by-step explanation:
How do I solve these measurement problems?

Perimeter of Triangle Please. Thank you ASAP
Step-by-step explanation:
The perimeter of a parallelogram is twice the sum of the length of a longer and a shorter side.
The length can be evaluated by the distance formula between two points (x_1,y_1), (x_2, y_2)
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For the longer side,
[tex]d=\sqrt{(7-(-4))^2+(3-2)^2}=\sqrt{122}[/tex]
or the shorter side,
[tex]d=\sqrt{(7-6)^2+(3-(-2))^2}=\sqrt{26}[/tex]
Therefore, the perimeter is given by,
[tex]2(\sqrt{122}+\sqrt{26})\approx254.2[/tex]

Answer:
7
Step-by-step explanation:
You've said that both triangle are equal.
This means, both are in proportion
Let the unknown side be x
4 : 5 : x = 36 : 45 : 63
Divide LHS by 9
4 : 5 : x = 4 : 5 : 7
Since you may see x and 7 are same. So, the missing side is 7.
Answer:
Step-by-step explanation:
[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex] #1 Find same sides
So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex] #2 fill it in.
36BC= 252 #3 Cross multiply.
[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex] #4 Divide by 36
BC= 7 #5 Here's your answer!
If you want to check, plug the sides in.
[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]
[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]
The siplified fractions should all equal the same number. If they do, the triangles are similar.

Evaluate 5k + 1 when: *
4 points
101 15 43 36 37 16 - 19 99 120
k = 3
k = - 4
k = 20
k = 7
k = 3
k = - 4
k = 20
k = 7
1
k^2 = 4k
k = 0, k = 4
#2
k^2 - 5k = k + 7
k^2 - 6k = 7
k^2 - 6k + 9 = 16
k - 3 = 4 ⇒ k = 7
k - 3 = -4 ⇒ k = -1
#3
k^3 - 5k^2 + 3k = -k
k^3 - 5k^2 + 4k = 0
k(k^2 - 5k + 4) = 0
k = 0, k = 1, k = 4

tom is 2 kg heavier than harry, who is 3 kg heavier than ben. when they add up all their weights, it comes to 65 kg. how many kg does harry weigh?
Answer:
Step-by-step explanation:
Let Harry = x
Tom = harry + 2
Tom = x + 2
Ben + 3 = harry
harry - 3 = ben
x - 3 = ben
Tom + harry + Ben = 65
x + 2 + x + x - 3 = 65
3x - 1 = 65 Add 1 to both sides
3x = 65 + 1
3x = 66 Divide by 3
x = 66/3
x = 22
So harry = 22 kg

HELP PLSPPPPPPPPPPPPPPP
Answer:
The equation is following the mathematical rule of multiplying exponents.
Step-by-step explanation:
As an example to back up the answer, when you have half of a dollar, that is $0.50, if you took a half (1/2) of $0.50 that would be one fourth (1/4) of a dollar, but half of 50 cents ($0.50) A similar thing is happening with this problem. When you have two numbers (2 and 4) when you multiply them together, they equal to eight (8) for this problem, when you multiply two exponents together, you are raising the coefficient (a real number like 6) to the power of 2, and then taking that number and multiplying it by the power of 4. This is similar to the half of 50 cents, is equal to 1/4 of dollar ($0.25)
Hope this helps explain multiplying exponents together, and the mathematical rule behind it.
