I am not sure what you mean, but x=4

Answer 2

In order to find the value of x, we can write the following statements and reasons:

Triangle PQR:

1. Statement: PS = PS

Reason: Reflexive property of equality

2. Statement: angle PSQ is congruent to angle PSR

Reason: Given

3. Statement: SQ is equal to SR

Reason: Given:

4. Statement: Triangle PSQ is congruent to triangle PSR

Reason: Case SAS of congruency

5. Statement: PQ is congruent to PR, so PR = 8

Reason: Corresponding sides of congruent triangles

Quadrilateral VSTU:

1. Statement: VT = VT

Reason: Reflexive property of equality

2. Statement: angle SVT is congruent to angle UVT

Reason: Given

3. Statement: angle VST is congruent to angle VUT

Reason: Given

4. Statement: Triangle VST is congruent to triangle VUT

Reason: Case AAS of congruency

5. Statement: ST = TU

Reason: Corresponding sides of congruent triangles

So we have 5z = 2z + 3. Solving for z, we have z = 1, so ST = 5z = 5

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?

Answers

Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Step-by-step explanation:

Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]

Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]

Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]

[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]

Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Tom has ⅞ cup of olive oil. He uses ½ cup to make salad dressing and ¼ cup to make tomato sauce. How much olive oil does Tom have left?

Answers

Answer:

1/8 cup left

Step-by-step explanation:

Starts with 7/8

Uses 1/2 which equals 4/8

Then uses another 1/4 which equals 2/8

4/8+2/8 is 6/8 so he uses 6/8 of olive oil

He has 7/8 and uses 6/8 so 7/8-6/8 quals 1/8

Assuming they bike the same path, will Hector catch up to Darnell before he gets home?

Answers

Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.

At the end of 6 years, the balance was $3,025. What is the interest rate on this account?

Answers

The percent is 5.25%

The interest rate on Mia's account is 20.17%.

What is the simple interest?

The borrowing amount is just the principal amount multiplied by the simple interest rate.

Given, Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.

The formula to calculate the simple interest is;

S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

We have, P = $2500 T = 6 years, S.I. = $3025

Substituting all the values in the formula;

3025 = 2500 x 6 x R / 100

R = 3025 x 100 / 15000

R = 20.17%

Therefore, the interest rate is 20.17%.

Answers

Answer:

(3, 1.5)

Step-by-step explanation:

Given the system:

6x + 8y = 30 y=1/2x

Substitute y and solve for x:

6x + 8y = 306x + 8(1/2x) = 306x + 4x = 3010x = 30x = 3

Find y:

y = 1/2xy = 1/2(3)y = 1.5

jack finds this list of ingridents needed to make 20 muffins. To make 20 muffins you need 220ml milk, 250g castel sugar, 400g flour.
Jack has these ingridents : 1 litre of milk, 750g caster sugar and 1.5kg flour. Work out the greatest number of muffins Jack can make with his ingridents!

Answers

Answer:

60 muffins

Step-by-step explanation:

20 muffins =

220 ÷ 20 = 11 (milk)

250 ÷ 20 = 12.5 (castel sugar)

400 ÷ 20 = 20 (flour)

Find out the greatest number of muffins Jack can make.

1 litre = 1000 ml

1000 ÷ 11 = 90.90 (recurring decimal) (milk)

Point VV is located at (-5,3)(−5,3) on the coordinate plane. Point VV is reflected over the yy-axis to create point V'V ′ . Point V'V ′ is then reflected over the xx-axis to create point V''V ′′ . What ordered pair describes the location of V''?V ′′ ?

Answers

Given:

Point V is located at (-5,3) on the coordinate plane.

It is reflected over the y-axis to create point V'.

Point V' is then reflected over the x-axis to create point V''.

To find:

The location of point V''.

Solution:

We have,

Point V= (-5,3)

If point V reflected over the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

A square has legs of 11, what is the measure of its hypotenuse

A.) 9.4 or B.)15.6

Answers

15.6 is the measure of the hypotenuse of the square.

What is a square?

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.

Given that one side of the square is 11.

The diagonal is the hypotenuse of the square.

Since square have equal sides, the hypotenuse can be obtained using Pythagorean theorem.

i.e. 11² + 11² = (hypotenuse)²

i,.e. (hypotenuse)² = 121+121 =242

Therefore, hypotenuse = √242 = 15.6

Hence, the measure of the hypotenuse of the square is 15.6
