What is the value of x in the solution to this system of equations?
3x+5y=94
x=2y−9

A.x = 7
B.x = 13
C.x = -13
D.x = 10

Answer:

AE = 26 units

Step-by-step explanation:

Given that ABC is congruent to EDC, therefore, the corresponding angles and corresponding lengths of ∆ABC and ∆EDC are equal to each other in measure.

AE = 2(AC) = 2(CE) or

AE = AC + CE

Let's find the AC using Pythagorean Theorem, since the ∆s are both right triangles.

BA is congruent to DE.

Since DE = 12 units, therefore, BA = 12 units.

BC = 5 units (given)

Using Pythagorean Theorem:

AC² = BA² + BC²

AC² = 12² + 5² (substitution)

AC² = 144 + 25 = 169

AC = √169

AC = 13 units

Since ∆ABC = ∆EDC, therefore:

AE = 2(AC)

AE = 2(13)

AE = 26 units

Answer:

1. [tex] x \ge -4 [/tex]

2. [tex] x < -2 [/tex]

Step-by-step explanation:

1. [tex] 10^{2x - 4} \le 1000^x [/tex]

Make both sides of the same base

[tex] 10^{2x - 4} \le (10^3)^x [/tex]

[tex] 10^{2x - 4} \le 10^{3x} [/tex]

Both bases will cancel each other

[tex] 2x - 4 \le 3x [/tex]

Subtract 2x from each side

[tex] - 4 \le 3x - 2x [/tex]

[tex] -4 \le x [/tex]

Rewrite

[tex] x \ge -4 [/tex]

2. [tex] (\frac{1}{5})^{3x + 10} > (\frac{1}{25}^{x + 4} [/tex]

Apply the inverse law of exponents

[tex] (5^{-1})^{3x + 10} > (25^{-1})^{x + 4} [/tex]

[tex] (5^{-1})^{3x + 10} > (5^{-2})^{x + 4} [/tex]

[tex] 5^{-3x - 10} > 5^{-2x - 8} [/tex]

Both bases will cancel each other

[tex] -3x - 10 > -2x - 8 [/tex]

Collect like terms

[tex] -3x + 2x > 10 - 8 [/tex]

[tex] -x > 2 [/tex]

Divide both sides by -1.

(Note: since we are dividing by a negative number, the inequality sign would change)

[tex] x < -2 [/tex]

Answer:

x^9

Step-by-step explanation:

When we multiply exponents with the same base, we add the powers

a^b * a^c = a^(b+c)

x^3 * x^6 = x^(3+6) = x^9

Step-by-step explanation:

[tex](x {}^{3}).( {x}^{6} ) = (x {}^{3 + 6} ) = {x}^{9} [/tex]

========================================

Explanation:

The ratio QR : RS : ST  is equal to 1 : 4 : 5

This means we have the following three equations

For some positive number x.

Note the ratio QR : RS : ST turns into x : 4x : 5x, which reduces to 1 : 4 : 5 when we divide all three parts by x .

Along with those three equations, we'll also use QT = 40 as well.

Now turn to the segment addition postulate. Plug in the equations mentioned earlier, and solve for x .

QT = QR + RS + ST

40 = x+4x+5x

40 = 10x

10x = 40

x = 40/10

x = 4

So we know that

QR = x = 4

RS = 4x = 4*4 = 16

ST = 5x = 5*4 = 20

-----------

As a check,

QR + RS + ST = 4 + 16 + 20 = 40

which is the same as QT = 40

Therefore, we've confirmed that QR + RS + ST = QT is correct and we've confirmed our answers.

Answer:

x = 110° ; y = 49°

Step-by-step explanation:

m∠ABD = m∠ADB = 35° ⇒ x = 180° - 2 × 35° = 110°  

m∠CDB = m∠CBD = 2y ⇒ y = (180° - 82°) ÷ 2 = 49°

Given:

The sum of three numbers is 12 .

The sum of twice the first​ number, 3 times the second​ number, and 4 times the third number is 37 .

The difference between 7 times the first number and the second number is 25.

To find:

The three number.

Solution:

Let the three numbers are x, y and z respectively.

According to the question,

[tex]x+y+z=12[/tex]           ...(i)

[tex]2x+3y+4z=37[/tex]         ...(ii)

[tex]7x-y=25[/tex]           ...(iii)

From (iii), we get

[tex]-y=25-7x[/tex]

[tex]y=-25+7x[/tex]

Put [tex]y=-25+7x[/tex] value in (i).

[tex]x+(-25+7x)+z=12[/tex]

[tex]8x-25+z=12[/tex]

[tex]8x+z=12+25[/tex]

[tex]8x+z=37[/tex]        ...(iv)

Put [tex]y=-25+7x[/tex] value in (ii).

[tex]2x+3(-25+7x)+4z=37[/tex]

[tex]2x-75+21x+4z=37[/tex]

[tex]23x+4z=37+75[/tex]

[tex]23x+4z=112[/tex]          ...(v)

Now, Multiply equation (iv) by 4 and subtract the result from (v).

[tex]23x+4z-4(8x+z)=112-4(37)[/tex]

[tex]23x+4z-32x-4z=112-148[/tex]

[tex]-9x=-36[/tex]

[tex]x=4[/tex]

Put x=4 in (iv).

[tex]8(4)+z=37[/tex]

[tex]32+z=37[/tex]

[tex]z=37-32[/tex]

[tex]z=5[/tex]

Put x=4 in [tex]y=-25+7x[/tex].

[tex]y=-25+7(4)[/tex]

[tex]y=-25+28[/tex]

[tex]y=3[/tex]

Therefore, the three numbers are 4, 3 and 5 respectively.

Answer:

50 seconds in order to assemble 20 pizza boxes

Step-by-step explanation:

there are two ways to solve this the first way is divide 20 by 2 which is 10 and then multiply 10 by 5 the reason to this is because we know that for every 2 it takes 5 seconds.

the second way takes longer but you write:

2, 2, 2, 2, 2, 2, 2, 2, 2, 2,

5, 5, 5, 5, 5, 5, 5, 5, 5, 5,

so here were basically writing the number 2 10 times because when u count that u can see that it equals 20 and then since for every 2 boxes it takes 5 seconds u put the 5 under each 2 so then you would count the 5s, like 5, 10 15, 20... and so on and u will see that its 50 which means 50 seconds.

Step-By-Step Explanation:

Answer:

32 pounds of almonds

Step-by-step explanation:

Monique sells nut mixes . She uses * 1/4 of her supply of almonds to make a nut mix and of her 5/8 supply to make a fruit and nut mix.

The total fraction of almonds that Monique used both for her but mix and fruit and nut mix =

1/4 + 5/8

Lowest common denominator is 8

1 × 2 + 5 × 1/8

2 + 5/8

= 7/8

If Monique uses 28 pounds of almonds

Let the total number of almonds = x

7/8 × x = 28

7x /8 = 28

Cross Multiply

7x = 8 × 28

x = 8 × 28/7

x = 32 pounds

Therefore, Monique initially had 32 pounds of almonds in her supply.

P'(3, - 3 )

Step-by-step explanation:

Given

M(- 3, 4 ) → M'(- 1, - 1 )

To obtain the image  2 is added to the x- coordinate and 5 is subtracted from the y- coordinate, that is

Translation rule is

(x, y ) → (x + 2, y - 5 ), thus

P(1, 2 ) → P'(1 +2, 2 - 5 ) → P'(3, - 3 )

Answer:

109 is 63% of 173.02

Step-by-step explanation:

Let 109 = 63% of x

Thus;

63/100 * x = 109

63x = 10900

x = 10,900/63

x = 173.02
