=8x+4y+7+22y
=(8x)+(4y+22y)+(7)
=8x+26y+7
Answer:
7 is the term
Step-by-step explanation:

because 22y is a coeifcent and a var and the rest of the equation is a coeifcent and a var. Besides 7 so 7 is the term
Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21 600 Find the number of cars that can be shipped if there are no trucks.
Answer:
6000 cars
Step-by-step explanation:
Each car weighs 3.6 tons and the ship can carry 21,600 so 21,600÷3.6 is 6000

Divide 3500 in the ratio 2: 2 : 3
Answer:
1000 : 1000 : 1500
Step-by-step explanation:
2 + 2 + 3 = 7
3500 ÷ 7 = 500
2 × 500 = 1000
2 × 500 = 1000
3 × 500 = 1500
1000 : 1000 : 1500
Answer:
1000 : 1000 : 1500
Step-by-step explanation:
you divide 3500 into 7 and find the answer = 500
then 500 x 2 = 1000,
500 x 3 = 1500
The baker is able to make a perfect pastry 97 of the time If he bakes 300 pies what is the probability that at least one doesn't turn out?
Answer:
there is a a 3% chance one doesnt turn out
Step-by-step explanation:
There is a one percent chance because 3(97/100)= 291/300 simplified we get back to 97/100 which is equal to 97%, 100-97=3 giving us 3%.
y = -x²+4
y = 2x+1
solve the system of equations
The solution of the equation as x= -1 then y= -1 and x= 3 then y = 7.
What is Equation?It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have equations y = -x²+4 and y = 2x+1.
So, 2x + 1 = -x²+4
x² - 4 -2x +1 = 0
x²-2x -3 = 0
Now splitting the mid term we get
x²-2x -3 = 0
x²-3x +x -3 = 0
x(x-3 ) + 1 (x-3)= 0
(x+ 1) (x-3) = 0
x= -1 or 3.
and, when x= -1 then y= -1
when x= 3 then y = 7.

or solve for x
x/ 4 + 8 /2=3.5
Find the measure of the exterior angle.
Answer:
120 degrees
Step-by-step explanation:
Because the triangle is a right triangle, it can be either a 45,45,90 triangle or a 30,60,90 triangle. I tested this problem with each scenerio, and I believe that it is a 30, 60, 90 triangle, with the top angle being 30 degrees, thus, making x=30. For the exterior angle, we'd multiply 4 by 30 to get 120 degrees.
I checked my answer by adding 120 to 60 (that's the degrees of the right hand corner of the triangle), which added to 180 degrees (aka a flat line), which verifies my answer.

Work out the surface area of this cylinder.
Answer:
Step-by-step explanation:
Total surface = πr² + 2πrh
Surface area = 22/7 × 6 × 6 + 2 × 22/7 + 25
So 22/7 × 12 + 44/7 × 25
Therefore this will give us 37.71 + 157.14
Therefore the total surface area of the cylinder is 194.85 cm².

if angle 1= 135, what is the measure of angle 2, and give your reason. Use the picture i used
Answer:
The measure of m∠2 is:
m∠2 = 45°Step-by-step explanation:
A straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line.
Given
The angle ∠ 1 = 135°.
It is clear that angles ∠ 1 and ∠ 2 lie on a straight line.
We know that a straight line is basically a straight angle i.e. 180°.
Thus,
The sum of angles ∠ 1 and ∠ 2 will be 180°.
i.e.
m∠1 + m∠2 = 180°
substitute m∠1 = 135° in the equation
135° + m∠2 = 180°
subtract 135° from both sides
135° + m∠2 - 135° = 180° - 135°
m∠2 = 45°
Therefore, the measure of m∠2 is:
m∠2 = 45°00:00

Answer:
Step-by-step explanation:
If a boat has the speed = 15 miles per hour
Let the speed of the river = v miles per hour
If the boat is moving down stream, that means boat is traveling with the stream of the river.
So the speed of the boat downstream = (15 + v) miles per hour
Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.

Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides

The length of each side of the playground is 20 ft.
What is a Square?
Square in geometry is a special kind of rectangle with four equal sides and four right (90°) angles.
Given is a square playground has an area of 400 square feet.
Area of square playground = 400 ft².
Area of square is given by square of the length of its sides. If 'a' is the side of a square, then mathematically we can write -
A [S] = a²
Using the formula discussed above -
a² = 400
a = √400
a = 20 ft
Therefore, the length of each side of the playground is 20 ft.

A selection box contains four types
of sweets: 6 caramels, 7 chocolates,
4 bonbons and 3 nougats
What fraction are carame/s
b. What fraction are not caramels?
Answer:
3/10 are caramel 7/10 are not caramel
Step-by-step explanation:
First you need to work out the total of sweets that is 6+7+4+3=20 sweets. Now it says that there are 6 caramels so you need to put 6/20 which can be simplified to 3/10. For b you have to work out the fraction that is not caramel so for this you have to add up 7+4+3=14 put 14/20 this can be simplified to 7/10.

WILL GIVE BRAINLIEST! Six numbers form an arithmetic sequence with a common difference of 4. The sum of these numbers equals to 12. What are the six numbers?
Answer: -8,-4,0,4,8,12
Step-by-step explanation:
The six numbers of the arithmetic progression are -8, -4, 0, 4, 8, 12
Arithmetic sequence:aₙ = a + (n - 1)dwhere
a = first term
d = common difference
n = number of terms
d = 4
first term = a
2nd term = a + 4
3rd term = a + (3 - 1) 4 = a + 8
4th term = a + (4 - 1) 4 = a + 12
5th term = a + (5 - 1) 4 = a + 16
6th term = a + (6 - 1) 4 = a + 20
sum of its 6 terms = 12
Therefore,
a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12
6a + 60 = 12
6a = 12 - 60
6a = -48
a = -48/6
a = -8
2nd term = -8 + 4 = -4
3rd term = -8 + 8 = 0
4th term = -8 + 12 = 4
5th term = -8 + 16 = 8
6th term = -8 + 20 = 12
