Answer: 32, 46

Step-by-step explanation:

a=number 1. b=number 2

a=b-14

a+b+7=85

b-14+b+7=85

b+b-14+7=85

2b-7=85

2b=92

b=46

a=46-14

a=32

Answer:



Step-by-step explanation:

the equation to find this is

x+(x+14)+7=85

first minus the 7

X+(x+14)+7-7= 85-7

x+(x+14)=78

78÷2 = 39

The decimal odd one out is: 123 hundredths and 4 thousandths.

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values.

Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given: 1.234 is a decimal.123.4 hundredths, 1234 thousandths and 12.34 are all different forms of the given decimal. But 123 hundredths and 4 thousandths is not.

This is due to the fact that in the other selections, it is written in decimal format or is finished, but in the fourth or final option, it is purposefully not written in decimals. It is hence the outlier.

Hence, The decimal odd one out is: 123 hundredths and 4 thousandths.

Answer: Brody's Age is 19 and Trinity's age is 11

Step-by-step explanation:

x = Trinity's age

2x-3= Brody's age

The sum of the ages is 30, so

x + (2x-3) = 30

3x - 3 = 30

add 3 to both sides 30 turns into 33 so,

3x = 33

divide by 3 both sides

x = 11 which is trinity's age and plug x  into 2x - 3 which is 19 so that's Brody's age.

We know that Mayerlin wants to ride her bicycle for 56 miles this week, and she already has ridden 8 miles, so the distance left is:

56mi - 8mi = 48mi

Now, to find the average distance that she needs to ride each day in order to meet her goal, we need to take the quotient between the distance left and the number days that she has left (6 days), then we will get:

D = 48mi/6 = 8mi

This means that if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.

Answer: Supplementary Angles

Step-by-step explanation:

Supplementary angles are a pair of angles whose sum is 180°. 45° and 135° add up to 180°. Therefore, the answer is supplementary angles.

The product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex] and g(x) = [tex]-x^{2}[/tex] is

As per the given question statement, we are supposed to find and simplify the product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex]and g(x) = [tex]-x^{2}[/tex].

Let's assume [tex]m(x)[/tex] be the product of the functions [tex]f(x)[/tex] and [tex]g(x)[/tex]

So, [tex]m(x) = f(x) * g(x)\\m(x)= (x+2)*(-x^{2} )\\m(x)=-x^{3} -2x^{2}[/tex]

Therefore the product of the functions f(x) and g(x), where the functions f(x) = [tex]x+2[/tex]and g(x) = [tex]-x^{2}[/tex] is [tex]m(x)=-x^{3} -2x^{2}[/tex]

Step-by-step explanation:

Solve for c:

a = -4 c + 4 b + 11 is equivalent to -4 c + 4 b + 11 = a:

-4 c + 4 b + 11 = a

Subtract 4 b + 11 from both sides:

-4 c = a + (-4 b - 11)

Applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

The linear pair theorem states that when two angles form a linear pair, the sum of both angles of the linear pair would be equal to 180 degrees.

Two angles that are a vertical pair, have a measure that is equal to each other, based on the vertical angles theorem. That is, they are congruent angles.

m<RQS + m<PQT = 180 degrees [linear pair theorem]

Substitute

(2m + 4)° + (3m + 1)° = 180°

Solve of the value of m

2m + 4 + 3m + 1 = 180

Add like terms together

2m + 3m + 4 + 1 = 180

5m + 5 = 180

5m + 5 - 5 = 180 - 5

5m = 175

5m/5 = 175/5

m = 35

m<PQR = 3m + 1 [vertical angles theorem]

Plug in the value of m

m<PQR = 3(35) + 1

m<PQR = 105 + 1

m<PQR = 106°

m<PQV = 1/2(m<PQR)

m<PQV = 1/2(106)

m<PQV = 53°

Thus, applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

Step-by-step explanation:

ΔFHE = ΔKHE, as the ∠FHE = ∠KHE. When two triangles contain the same two sides and include the same Angle, the remaining sides, Angle, and area are likewise identical, which means they're congruent.

∠FHE ≅ ∠KHE is an Identical part.

L(FE) = L(KE), as two Congruent angles have equal sides

L( FH) = L(KH)

L(EH)=L(EH),  Common part in a figure.

Congruent angles are two or more angles that are exactly the same. As a result, the lengths of these angles are identical.

hence, ΔFHE = ΔKHE, as the ∠FHE = ∠KHE. When two triangles contain the same two sides and include the same Angle, the remaining sides, Angle, and area are likewise identical, which means they're congruent.

The investment amount at 9% rate is $12500 and the investment

amount at 2% rate is $15500

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Let x be the amount invested at 9% rate.

And (28000−x) be the amount invested at 2% rate.

The total annual income is $1435

Let us find the amount invested at 9% rate:

x9%+2%(28000−x)=1435

9%+2%(28000−x)=1435

0.09x+0.02(28000−x)=1435

0.09x+560−0.02x=1435

0.09x−0.02x=1435−560

0.07x=875

x=875/0.07

x=12500

Let us find the investment amount at 2% rate:

⇒28000−x

⇒28000−12500

⇒15500

to get an average, you add up all the factors then divide them by how many there are. I added 500 12 times to 1250 12 times to 1150 3 times and 600 4 times.

aka (500*12)+(1250*12)+1150+1150+1150+600+600+600

then i divided by 31 because 12+12+3+4=31. giving the average $866.13.
