Answer:

x=3 and y=2

Step-by-step explanation:

first you rearranging the values

2x - y = 4 ...............(i

3x + y = 11 ..............(ii)

make y the subject of formular from ii

y=11 - 3x .............(iii

substitutes equ. (iii) into (i)

2x - (11-3x) = 4

2x - 11 + 3x = 4

5x = 15

x = 3

substituting x into equ. (iii) we have:

y = 11 - 3(3)

y = 11 - 9

y = 2

Answer:

X = 3 and Y = 2

Good Luck!!

Answer:

Below!

Explanation:

Exponents are small numbers that defines how many times does the base needs to multiply itself. Two exponents can also be classified in words. 'Squared' defines a number multiplying itself two times. 'Cubed' defines a number multiplying itself three times. If there is a zero as the base's exponent, this means that the result will always be 1. Now, let's solve all the problems together.

Answer:

3x-10=56

3x=56+10

3x=66

3x/3 = 66/3

x=11

79-y=2x

79-y=2(11)

79-y=22

79-22=y

y=57

therefore x=11 and y=57

3x-10=56

79-y=2x    so y=-2x+79

(Solve 3x−10=56 for x):

3x−10=56

3x−10+10=56+10 (Add 10 to both sides)

3x=66

(Divide both sides by 3)

x=22

(Substitute 22for x in y=−2x+79):

y=−2x+79

y=(−2)(22)+79

y=35 (Simplify both sides of the equation)

Answer:

x=22 and y=35

Answer:

x = 28

Step-by-step explanation:

The angle is 90 degrees. (right angle)

Based on the information given, part of the angle is 33 degrees.

Given this information, 2x + 1 = 90 - 33

90 - 33 = 57

2x + 1 = 57

2x + 1 - 1 = 57 - 1

2x = 56

56 / 2 = 28

Answer:

x=28

Step-by-step explanation:

1) 2x+1+33= 90

2) 2x+34=90

3) 2x= 56

4) x= 28

i dont understand the second question we study in french :(

Step-by-step explanation:

look at the green point.

what is the closest whole number to the green point ?

to me it is very clearly 35.

you understand what a whole number is ?

it is a number without any fractional part.

so, like 1, 2, 3 ...

and not like 1.5, 0.33, 17.892 ...

and the nearest ten (number)?

what that means is something like 10, 20, 30, ...

so, clearly, from the position of A, it is closer to 40 than to 30 (as it is right of the middle 35).

therefore, A rounded to the nearest ten is 40.

Answer:

1 and 1/4 cups of floour is used to make one pie. Since 7 and 1/2 cups is used for 6 pies we divide the 7 and 1/2 cups by the 6 pies. 7 and 1/2 cups is equivalent to 15/ 2 cups. 15/2 divided by 6 is equal to 15/2 times 1/6. This comes out to 15/12, which simplifies to 5/4, which is equivalent to 1 and 1/4 cups

Answer:

well i was oin to search up how many cups of four are in a pie but it didnt show, it just showed how to make a pie or something but i think what uou would do is divide 12 by 1/4 which would be 3 cups of flour

Step-by-step explanation:

1) divide 12 to 1/4

2) =3

for 7 pies you need 21 cups of flour and for one you need 3

Answer:

201 square inches

Step-by-step explanation:

The length of the model is 3 times that of the actual stadium

Given the scale model of a football stadium to be 1:360

If the actual length is 120yards, the length of the football field will be expressed as:

L = 120/360

L = 1/3 yards

L = 1/3 * 36 = 12 inches

Length of the actual stadium = 40 yards

Length of the new stadium = 120 yards

Let x be the multiply

40x = 120

x = 3

Hence the length of the model is 3 times that of the actual stadium

The requried, 9x² + 6x can be fully factorised as 3x(3x + 2).

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

To factorize fully 9x² + 6x, we can factor out the most significant common factor of the two terms, which is 3x:

9x² + 6x = 3x(3x + 2)

Therefore, 9x² + 6x can be fully factorised as 3x(3x + 2).

You can use the distributive property of multiplication over addition to find the equivalent expression to the given expression.

The expression which is equivalent to the given expression is given by

Option D: [tex]7y(-4x + 5)[/tex]

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a \times b + a \times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The given expression is [tex]-28xy + 35y[/tex]

Since 28 = 7 times 4 and 35 = 7 times 5

Thus,

[tex]-28xy + 35y = -7 \times 4 \times x \times y + 7 \times 5 \times y = 7y(-4x + 5)[/tex]

Answer: Choice C

{1, 1, 2, 3, 5}

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

We have

[tex]a_1 = 1\\a_2 = 1[/tex]

Showing the first two terms are 1,1.

The answer is between choices B and C because of this.

To get the nth term [tex]a_n[/tex], we add up the two previous terms before it [tex]a_{n-1}[/tex] and [tex]a_{n-2}[/tex]

So to get the third term [tex]a_3[/tex], we'll add up the first two terms

[tex]a_n = a_{n-2} + a_{n-1}\\\\a_3 = a_{3-2} + a_{3-1}\\\\a_3 = a_1 + a_2\\\\a_3 = 1 + 1\\\\a_3 = 2[/tex]

The third term is therefore 2.

The sequence so far is {1,1,2} which matches with the first three terms of choice C.

Then we can say:

[tex]a_4 = a_2 + a_3\\\\a_4 = 1+2\\\\a_4 = 3[/tex]

Further confirming the answer. I'll let you check the next set of terms.

Answer:

no

Step-by-step explanation:

Since there is a $25 yearly registration fee, the total price will never be directly proportional to the number of days visited because if the number of days visited is multiplied by 9, it will have a leftover yearly registration fee, which cannot be accounted for unless written with a function.
