Solve the system of equations-2x+3y=-1 and 7x-8y=16 by combining the equations

Answer:

Step-by-step explanation:

14x5-22

Answer:

Just input sin(9), sin(30), sin(81), etc.

For this set, you need a scientific calculator or else, you won't be able to answer that. There is a way but that is already obsolete now.

Answer:

1 1/2

Step-by-step explanation:

its 100% correct.

Answer:

the answer would be D40 because if you have 15 you take and you subtract the six from it and you wouldn't get 0.6 or 0.4 so those to A&B or eliminated but C & D where would be the only two would left and it would be D because 6 and 9 or almost equal to each other so it would be. 40 which sould be D

Answer:

option 2 , 3 , 4 , 5

Step-by-step explanation:

Use Pythagorean theorem

hypotenuse² = base² + altitude².

If the lengths satisfies Pythagorean rule, then they form a right angle triangle.

2) 41² = 40² + 9²

1681 = 1600 + 81

1681 = 1681

41, 40 , 9 will form a right angle as it satisfies Pythagorean rule.

3) 15² = 12² + 9²

225 = 144 + 81

225 = 225

9, 12 , 15 will form a right angle as it satisfies Pythagorean rule.

4) 17² = 15²  + 8 ²

289 = 225 + 64

289 = 289

17, 15 , 8  will form a right angle as it satisfies Pythagorean rule.

5)53² = 28² + 45²

2809 = 784 + 2025

2809 = 2809

53 , 28 , 45 will form a right angle as it satisfies Pythagorean rule.

Step-by-step explanation:

Answer:

60 because [total of pizzas]/(veggie + cheese)= 12 ((108/(4+5) = 12)) so you take 5 (the amount of cheese pizzas) and multiply it by 12 to get 60

sorry if i explained it bad im not too good at explaining

Answer:

Step-by-step explanation:

when you combine the amount of almonds and raisins, you get 12 ounces. so out of those 12 ounces, 7 is going to be almonds. aka [tex]\frac{7}{12}[/tex]. now you just have to multiply that by 16 (since there are 16 ounces in a pound) and you'll get roughly 9.333

Answer:

Algebracicaly speaking the answer would be either -13.3876 or - 158.612 through the quadratic equation, but these answers don’t make sense in this real world scenario.

Step-by-step explanation:

Answer:

B.) |w - 5.76| / 36 = 0.03

Step-by-step explanation:

Given :

Weight of individual candy piece = 0.16 ounce

Number of candy pieces per package = 36

Allowable variation in weight of individual piece = 0.03 ounces

The highest and lowest allowable weight, w of a package of 36 pieces ;

Actual manufacturing weight of entire 36 candy = (36 * 0.16) = 5.76

Allowable weight ± actual weight ≤ allowable variation

w ± 0.16 ≤ 0.03

|w - 0.16| ≤ 0.03

For the entire 36 candy pieces :

|w - 0.16*36| = 0.03 * 36

|w - 5.76| = 1.08

|w - 0.16*36| = 0.03 * 36

Could also be written as :

|w - 5.76| / 36 = 0.03

Answer:1 : 22.5

2 : 20 games

3 : 575

4 : Grant can purchase 7 base ball cards packs in $21

Step-by-step explanation: OK first divide 90 by 4 to see how many words per minute

1# 90 ÷ 4 = 22.5

OK, then multiply 22.5 by 10 for your answer

Your answer is;

225 words per 10 minutes

2#Hope I Helped!!! 7*4=28 and 5*4=20 so about 20 games.

3# 2p=230

divide 2

Each slice of pizza is 115 calories.

5p=c

5(115)=c

575= Calories

Grant paid $12 for 4 baseball card packs.

So, in $1 he will purchase, cards

And in $21, he will purchase = 7

Therefore, Grant can purchase 7 base ball cards packs in $21.

Answer:

[tex]1\frac{1}{9} ft^{3}[/tex]

Step-by-step explanation:

One cube is 1/3 x 1/3 x 1/3 or 1/27

In the rectangular prism there are 30 of those small cubes.

30 * 1/27 = 30/27= [tex]1\frac{3}{27}[/tex] or  [tex]1\frac{1}{9} ft^{3}[/tex].
