[tex]x1+2x2-x3=3, 2x1+x2-2x3=1, 3x1+4x2-5x3=5[/tex]

Answers

Answer: x1 = 0; x2 = 5/3; x3 = 1/3

x1 + 2x2 - x3 = 3 => 2x1 + 4x2 - 2x3 = 6

2x1 + x2 - 2x3 = 1

=> 4x2 - x2 = 5

⇔ 3x2 = 5

⇔ x2 = 5/3

with x2 = 5/3, we have: x1 - x3 = 3 - 10/3 = -1/3

3x1 - 5x3 = 5 - 4.5/3 = -5/3

=> x1 = 0

x3 = 1/3

Suppose Anthony Ianni attempted 18 baskets in a basketball game. If the ratio of baskets made to baskets missed is 1:5, how many baskets did Ianni make?

Answers

Answer:

Number of baskets Lanni make = 3 basket

Step-by-step explanation:

Given:

Total attempt = 18 times

Ratio(Basket make : Basket missed) = 1:5

Find:

Number of baskets Lanni make

Computation:

Number of baskets Lanni make = Total attempt x [Basket make ratio]

Number of baskets Lanni make = 18 x [1/(1+5)]

Number of baskets Lanni make = 3 basket

I only need help on questions 6 and 7. (Use the congruent figure on top to answer 6 and 7.)

Answers

Answer:

See below.

Step-by-step explanation:

All statements of congruent angles and congruent segments are correct.

A similarity statement can be written ...

Write a similarity statement ...

ABCD ~ HJKL

The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.

This is the correct reason:

"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."

"A similarity ratio is a ratio that compares the lengths of the corresponding sides of two similar polygons. The ratio is written in the same order as the two

polygons."

For the similarity ratio, we use two corresponding sides.

AB = 8; HJ = 12

AB/HJ = 8/12 = 2/3

The similarity ratio of ABCD to HJKL is 2/3.

Step-by-step explanation:

I am not exactly sure, but you can't divide x and y, which would already make the question null and void. The simplest form would be the form it is in right now.

A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. The number of multiple-choice questions minus the number of
short-answer questions is 60.
OB. The number of multiple-choice questions times the number of
short-answer questions is 15.
C. The number of multiple-choice questions plus the number of
short-answer questions is 15.
D. The number of multiple-choice questions plus the number of
short-answer questions is 60

Answers

Answer:

C. The number of multiple-choice questions plus the number of

short-answer questions is 15.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of multiple-choice questions

y is the number of short-answer questions.

Multiple-choice questions are worth 2 points, and short-answer questions are worth 5 points.

This means that:

[tex]2x + 5y = 60[/tex]

The test has 15 questions.

This means that:

[tex]x + y = 15[/tex].

Which means that option C is the correct answer.

Answer:

C. The number of multiple-choice questions plus the number of short-answer questions is 15.

Step-by-step explanation:

x + y = 15

1) 10 weeks. The total will be $550 after tax, and then you subtract what he has already. You’re left with $385 left to have enough. He’ll have a bit more after the 10th week. It will take 10 weeks to save the amount.
Step-by-step explanation:
The price of Xbox one = $500
Sales tax = 10%
The total cost of Xbox one = 500 + (10% × 500 )
= 500 + (0.010 × 500)
= 500 + 50
= $550
Anakin currently has = $165
He earns per week = $40
Let the time (in weeks) will take for him to save the amount be t
165 + (40t) = 550
40t = 550 - 165
40t = 385
t =
t = 9.625 ≈ 10 weeks
It will take 10 weeks to save the amount.

(D) 707 feet

Answers

Answer:

47 feet

Step-by-step explanation:

Shawn is placing a fence around a circular garden with diameter of 15 foot

π = 3.14

Therefore the circumference can he calculated as follows

= π × diameter

= 3.14 × 15

= 47.1 feet

Hence the circumference to the beatesr tenth is 47 feet

of the photo is 33/20 square inches, what is the width of the photograph? *

Answers

Answer:

1.12 × 10^-3

Step-by-step explanation:

The computation of the width of the photograph is as follows:

As we know that

Area of the rectangle = length × width

33 ÷ 20 square inches = 1475 inches × width

So, the width is

= Length ÷ area

= 1475 inches ÷ (33 ÷ 20 square inches)

= 1.12 × 10^-3
