Answer:
6x+4y=16
Step-by-step explanation:
2 ( 3x) + 2 (2y) = 2 (8)
6x + 4y = 16 <===== add this equation to the top equation to get
11x = 22
then x = 2 use this value of x in any of the equations to calculate y
5(2) - 4y = 6
10 - 4y = 6
-4y = -4
y = 1

When planning space exploration, scientists face many
challenges. One issue is the weight of the items being
transported. They can use the engineering design process
to help minimize the weight of materials on board a
spacecraft.
The engineering design process starts with a statement of the problem to be
solved. Which sentence best states the problem described above?
O A. Metal is stronger than plastic, but it is also much heavier.
OB. Space vessels must carry heavy equipment but also minimize
weight.
O C. The longer a space flight will last, the more equipment must be
carried
D. Lower gravity on the Moon means that objects weigh less on the
Moon than on Earth.

A rectangle has an area of 54 sq. cm and a length of 6 cm. Find its width
Answers
Answer:
9 cm
Step-by-step explanation:
A= lw
54=6w
9=w
Answer:
9 cm
Step-by-step explanation:
⇒ Area of rectangle = (L)(B)
Substitute the length, breadth, and the area in the formula:
⇒ Area of rectangle = (L)(B) = 54 cm²
⇒ (6)(B) = 54 cm²
Divide 6 both sides:
⇒ (6)(B)/6 = 54/6 cm²
⇒ B = 9 cm
Thus, the measure of the width is 9 cm.

Step-by-step explanation:
First, we know that the area of the rectangle is L x W.

A bag of apples weighs 6 2/7 pounds . A crate of bananas is 4 times as heavy as the apples. How much heavier are the bananas than the apples
Answers
Work:
6.29 = apple weight
6.29•4=25.16
25.16 = banana weight
25.16-6.29=18.87
18.87 is the difference between the apples and bananas so therefore is how much heavier the bananas are
Call the weight of the bag of apples as x (x = 6 2/7)
Since the crate of bananas is 4 times as heavy as the apples -> the crate of bananas = 4x
So, to find the weight difference, we minus those : 4x - x = 3x
Now we convert this : 3x = 3 x 6 2/7 = 132/7
Convert to :
Mixed : 18 6/7

What are all the values of x that make the inequality 8 - 3x < 20 true?
Answers
Let's solve this inequality.
First of all, subtract 8 from both sides:-
[tex]\sf{-3x < 20-8}[/tex]
[tex]\sf{-3x < 12}[/tex]
Divide both sides by -3:-
[tex]\sf{x > -4}[/tex]
Notice that the inequality sign changed...
Here's the rule:-
When you multiply/divide both sides by a negative number, you flip the inequality sign; so if we have "less than" it becomes "greater than" and so on...
So these are the values of x that will make the inequality true:-
[tex]\bigstar{\boxed{\pmb{The~numbers~greater~than~-4}}}[/tex]
Well, -3 is greater than 4 :)
Let's plug it in and see if it makes the inequality true:-
-3>-4
Yes, it does make the inequality true :)
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
Writing an equation in slope-intercept form given
A line passes through the point (-1, 8) and has a slope of -9.
Write an equation in slope-intercept form for this line.
Answers
Answer:
y = -9x - 1
Step-by-step explanation:
Step 1:
y = 8, x = -1
By putting the above values in equation (i)
8 = -9 (-1) + b
8 = 9 + b
-1 = b
b = -1
y = -9x - 1

Kristine observes the top of a lookout tower from a point 220 ft from its base.
If the indicated angle of elevation measures 37º, how tall is the tower? Give your answer to the nearest tenth of a foot.
Answers
Answer:
165.8 ft (nearest tenth)
Step-by-step explanation:
We can use the tan trig ratio to calculate the height of the tower.
[tex]\sf tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] = the angleO = the side opposite the angleA = the side adjacent the angleFrom inspection of the diagram:
[tex]\theta[/tex] = 37°O = height of tower (let's call this h)A = 220 ftSubstituting these values into the trig tan ratio:
[tex]\sf \implies tan(37)=\dfrac{h}{220}[/tex]
Multiply both sides by 220:
[tex]\sf \implies 220tan(37)=h[/tex]
[tex]\sf \implies h=220tan(37)[/tex]
[tex]\sf \implies h=165.781891[/tex]
Therefore, the height of the tower is 165.8 ft (nearest tenth)
Noah is making grilled cheese sandwiches for friends. He has 24 ounces of cheese. He plans to split the cheese evenly between 6 sandwiches.
Write an equation to determine how many ounces of cheese, ccc, Noah can use on each sandwich.
Answers
Answer:
24 / 6 = ccc
Step-by-step explanation:
There is 24 oz of cheese total that will be split evenly (divided) into 6 parts.
Each part will equal one sandwich worth of cheese (ccc) on the other side of the equation.
This one is very simple to solve, you could just calculate 24/6 to get your answer. But I'll go through it using typical algebra you would use for a less simple equation.
To solve:
Multiply by 6 to cancel the division by 6 on the left side
24 = 6ccc
Divide by 6 to isolate ccc again
4 = ccc
So each sandwich would get 4oz of cheese.
