what is the answer to 6−2(3x−5)=−8

Answers

Answer:

x = 4

Step-by-step explanation:

6-2(3x-5)=-8
So first we distribute:
6-6x+10=-8
Combine like terms:
16-6x=-8
Now subtract 16 to -8:
-6x=-24
Divide -6 to both sides:
x=4

Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs pound, a navel orange that weighs pound, and a pear that weighs 0.5 pound. What is the order of the fruit from least

Answers

Answer:

The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

Step-by-step explanation:

P.S - The exact question is -

Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs [tex]\frac{3}{4}[/tex] pound, a navel orange that weighs [tex]\frac{5}{8}[/tex] pound, and a pear that weighs 0.5 pound.

To find - What is the order of the fruit from least weight to the greatest weight ?

Proof -

Weight of apple = 0.45 pound

Weight of grapefruit = [tex]\frac{3}{4}[/tex] pound = 0.75 pound

Weight of navel orange = [tex]\frac{5}{8}[/tex] pound = 0.625 pound

Weight of a pear = 0.5 pound

As,

0.45 < 0.5 < 0.625 < 0.75

So, The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

62% of trees were saved from a fire. If this represents 1420 trees, how many trees were originally in the forest?Round to the nearest whole tree.

Answers

Answer:

2290 trees

Step-by-step explanation:

Given data

Let the total number of trees be x

62% of the total trees x is 1420 trees

mathematically

62/100x= 1420

0.62x= 1420

divide both sides by 0.62

x= 1420/0.62

x= 2290.32

To the nearest whole tree= 2290 trees

A baker needs 15 lb of cream cheese that contains 20% fat to fill a big order. But his supplier delivers one cream cheese that contains 10% fat, and another that contains 35% fat. How many pounds of each should the baker combine to fill the order?​

Answers

Answer:

6 2/3 lbs of each

Step-by-step explanation:

.10x + .35x = 15(.20)

.45x = 3

x = 3/4.5

x = 6.67

Answer:

Step-by-step explanation:

[.1x+.35(15-x)]/15=.2

.1x+5.25-.35x=3

-.25x+5.25=3

-.25x=-2.25

x=9

So he will use 9lbs of 10% and 6lbs of 35%.

Xander goes to the movies with his family. Each family member buys a ticket and two boxes of popcorn. There are five members of his family. Let t represent the cost of a ticket and p represent the cost of a box of popcorn. Explain how each expression describes the situation in a different way.

Answers

Answer:

t + 2p = cost of 1 family member

Step-by-step explanation:

Because there are 5 family members who buy 1 ticket and 2 boxes of popcorn, we must multiply the cost of one family member by five .

5(t + 2p) = total cost of the whole family.

We can distribute 5 and the above equation will become.

5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.

Hope that helps! :)

Answer:

Step-by-step explanation:

t + 2p = cost of 1 family member

since there are 5 family members who bought one ticket and 2 popcorn, we simply multiply the cost of 1 family member by 5.

5(t + 2p) = total cost of the whole family.

We can distribute 5 and the above equation will become.

5t + 2(5)p ⇒ 5t + 10p = total cost of the whole family.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

x/a + y/b = 1

Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.

The equations are given below.

5x + 7y = 1

x + 4y = -5​

Convert the equation into an intercept form. Then we have

From equation 1, then we have

5x + 7y = 1

x / (1/5) + y / (1/7) = 1

From equation 2, then we have

x + 4y = -5​

x / (-5) + y / (-5/4) = 1

The lines are drawn below.

Then the intersection point is (3, -2). Then the solution of the equations will be (3, -2).

what is the surface area of the figure?

Answers

Answer:

96

Step-by-step explanation:

first off you know that it is a square pyramid, so you can assume that all base lengths are 6.

i am going to find the base first. it is 36 because 6*6-36 save this in your mental memory

next, we have to find the 4 triangles

we know that they are 5 by 6 but you have to divide them by 2

so 30/2=15 and there are 4 of them

15*4=60

now add together 60 and 36 and you get 96

Answer:

The values of [tex]f[/tex] and [tex]g[/tex] are, respectively:

[tex]f = 6\,cm[/tex], [tex]g = 8\,cm[/tex]

Step-by-step explanation:

The area of the triangle ADE is:

[tex]A_{ADE} = 60\,cm^{2}-48\,cm^{2}[/tex]

[tex]A_{ADE} = 12\,cm^{2}[/tex]

The area of the triangle is defined by the following formula:

[tex]A_{ADE} = \frac{1}{2}\cdot AD\cdot DE[/tex] (1)

If we know that [tex]A_{ADE} = 12\,cm^{2}[/tex] and [tex]DE = 4\,cm[/tex], then the length of the line segment [tex]AD[/tex] is:

[tex]AD = \frac{2\cdot A_{ADE}}{DE}[/tex]

[tex]AD = 6\,cm[/tex]

And the area of the rectangle is:

[tex]A_{ABCD} = AD\cdot CD[/tex] (2)

If we know that [tex]A_{ABCD} = 48\,cm^{2}[/tex] and [tex]AD = 6\,cm[/tex], then the length of the line segment [tex]CD[/tex] is:

[tex]CD = \frac{A_{ABCD}}{AD}[/tex]

[tex]CD = 8\,cm[/tex]

Hence, the values of [tex]f[/tex] and [tex]g[/tex] are, respectively:

[tex]f = 6\,cm[/tex], [tex]g = 8\,cm[/tex]

Answers

Answer:

628.4cm²

Step-by-step explanation:

Find the diagram attached

Area of the semi circle = πr²/2

r is the radius = 10cm

Area of the semi circle = π(10)²/2

Area of the semi circle = 3.142(100)/2

Area of the semi circle = 314.2×2cm²

Area of the semi circle =628.4cm²

Hence the area of the semicircle is 628.4cm²

100 degrees

Step-by-step explanation:

hi again,

By the linear pair theorem, Angle B + Angle E will equal 180 degrees

Angle B + 128 = 180

Angle B = 52

By the triangle Sum Theorem, Angle A + Angle B + Angle C = 180

48 + 52 + Angle C = 180

100 + Angle C = 180

Angle C = 80

Like I said, by the linear pair theorem, Angle C + Angle F will equal 180 degrees

80 + Angle F = 180

Angle F = 100
