I need help figuring out the answers

need pic pls so I can answer your questions

Answer:

x = 10

y = 15

Step-by-step explanation:

5x − 4y = −10  ⇒  ( 1 )

y = 2x − 5     ⇒ ( 2 )

Let us find the value of x.

For that, we can replace y with ( 2x - 5 ).

Let us take equation 1.

5x − 4y = −10

5x - 4 (  2x − 5 ) = -10

5x - 8x + 20 = -10

-3x = -20 - 10

-3x = - 30

Divide both sides by ( -3 ).

x = 10

And now let us find the value of y.

Let us take equation 2.

y = 2x − 5

y = 2 × 10 - 5

y = 20 - 5

y = 15

Answer:

X=10

Step-by-step explanation:

5x-4y=-10.....1

y=2x-5......2

sub 2 into 1

5x-4(2x-5)=-10

5x-8x+20=-10

5x-8x=-10-20

-3x=-30

x=10

sub x=10 into 2

y=2(10)-5

y=20-5

y=15

Answer:

14 m²

area of sqaure pyramid: a² + 2(a)(l)

area:

Total milligrams

COST PER MG:-

Answer:

$3.17

Step-by-step explanation:

1 pill = 3 mg

⇒ 45 pills = 45 × 3 = 135 mg

45 pills = $427.95

⇒ 135 mg = $427.95

⇒ 1 mg = $427.95 ÷ 135 = $3.17

Answer: D

Step-by-step explanation:

[tex]\log _{3}\left(2 x y^{3} z^{5}\right) \\ =\log _{3} 2+\log _{3} x+\log _{3} y^{3}+\log _{3} z^{5}[/tex]

[tex]\left(\because \log _{c}(a \cdot b)=\log _{c} a+\log _{c} b\right)[/tex]

[tex]=\log _{3} 2+\log _{3} x+3 \log _{3} y+5 \log _{3}z \rightarrow \left(\because \log _{c} a^{b}=b \log _{c} a\right)[/tex]

Therefore, Option D is the correct answer

Answer:

x = 5

Step-by-step explanation:

Any number over 0 is undefined. Given that, the values of x that make this expression undefined make the denominator equal to 0

x - 5 = 0

x = 5

Answer:

50 times.

Step-by-step explanation:

When the 2 number cubes are rolled once:

The possible outcomes for a total of 7 are:

1 and 6

6 and 1

2 and 5

5 and 2

3 and 4

4 and 3

= 6 outcomes.

The total of all possible outcomes = 6 * 6 = 36.

So Prob( total of 7 in one throw of teh 2 cubes) =  6/36 = 1/6.

For 300 throws you would expect the total of 7 to occur

1/6 * 300 = 50.

Answer:

Step-by-step explanation:

50 IS THE ANSWEr

Answer:

Collinear points: points that lie on the same straight line or in a single line

Coplanar points:  three or more points which lie in the same plane

12. Point collinear with points E and G = C. Point Y

13. Point coplanar with points A, D and H = A. Point E

14. Point coplanar with points A, C and G = A. Point E

15. Point collinear with points B and D = B. Point X

Answer: -6

Step-by-step explanation:

The graph of g is the graph of f translated left 6 units.

Answer:

A = 44.42°

Step-by-step explanation:

SohCohToa

Soh = sin(theta)= opp/hyp

Coh = cos(theta)= adj/hyp

Toa = tan(theta)= opp/adj

Coh = cos(theta)= adj/hyp

cos(A)= adj/hyp

cos(A)= 5/7

A = cos^-1(5/7)

A ≈ 44.4153086

A = 44.42°

Answer:

We can think of our denominator as 6 in our probability, because there are 6 total sides to this die.

Out of those 6 sides, they want to find out if we can roll a number less than 3.

First, let's find how many numbers there are on this die that are less than 3.

1 and 2, so there are 2 sides that contain numbers less than 3 on this die.

So there is a 2 out of 6 chance(2/6) which can be simplified to 1/3, of selecting a number less than 3 when rolling a die.

1/3 probability.

Convert this into a percent if you'd want:-

1/3 · 100

= 33.333... which can be rounded to a 33% probability.

Answer:

6.7kg - 2.6kg = 4.1kg

Step-by-step explanation:

6 7/10 is equal to 6.7. If we have 6.7kg of pumpkins, but we can't use 2.6kg, then we subtract to find the amount that we can use.

Answer:

In 4 years you will get 44 and in 4 years and 6 months you will get 49.5

Step-by-step explanation:

550*0.02= 11 (yearly interest)

11*4 years= 44

11/12months=0.917

0.917*6 months= 5.5

44+5.5=49.5 (4 years and 6 months interest)

Answer:

  square

Step-by-step explanation:

A quadrilateral with four right angles will be a rectangle. A rectangle with sides of equal length is a square.

Jeremy's picture is a square.

Step-by-step explanation:

If 4 hamburger = $21.25

1 hamburger = x

Cross multiply

4 x x = $21.25 x 1

4x = $21.25

Devide both side with the coefficient of x

4x/4 = $21.25/4

X = $5.3125

Therefore 1 hamburger cost $5.31

If 4 hotdogs = $22.75

1 hotdog = y

Cross multiply

4 x y = $22.75 x 1

4y = $22.75

Devide both sides with the coefficient of y

4y/4 = $22.75/4

Y = $5.6875

Therefore one hotdog cost $5.69
