Step-by-step explanation:
elimination of x:
-6x +5y = 1
6x + 4y = -10
___________+
9y = -9
y = -9/9 = -1
elimination of y:
-24x +20y = 4
30x + 20y = -50
_____________-
-54x = 54
x = 54/-54 = -1
{ -1, -1}
[tex]\huge{ \mathcal{ \underline{ Answer }\: \: ✓ }}[/tex]
The given equations are :
[tex]\longrightarrow - 6x + 5y = 1[/tex]
[tex]\longrightarrow6x + 4y = - 10[/tex]
let's add the equations
[tex] \longrightarrow\small{ - 6x + 5y +6x + 4y = 1 + ( - 10)}[/tex]
[tex]\longrightarrow9y = - 9[/tex]
[tex]\longrightarrow y = - 1[/tex]
now, let's plug the value of y in first equation :
[tex]\longrightarrow - 6x + (5 \times - 1) = 1[/tex]
[tex]\longrightarrow - 6x - 5 = 1[/tex]
[tex]\longrightarrow - 6x = 6[/tex]
[tex]\longrightarrow x = - 1[/tex]

At a bakery, 6 ½ quarts of cake mix can be used to bake 3 ½ cakes. If 14 cakes are going to be baked, how many quarts of cake mix will be needed? *
Just show your work, and explain how you did it!
Answer:
26 quarts
Step-by-step explanation:
[tex]6\frac{1}{2} = \frac{13}{2}\\\\3\frac{1}{2} = \frac{7}{2}[/tex]
Quarts Cake
[tex]\frac{13}{2}[/tex] [tex]\frac{7}{2}[/tex]
x 14
find x.
Cross multiply to find x.
[tex]x \times \frac{7}{2} = 14\times \frac{13}{2}\\\\\frac{7x}{2} = 7 \times 13\\\\7x = 7 \times 13 \times 2\\\\x = \frac{7 \times 13 \times 2}{7} = 26[/tex]
So you need 26 quarts for 14 cakes

Answer:
x = 37
Step-by-step explanation:
The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles
Vertical angles are congruent ( equal to each other )
Hence, 74 = 2x
^(note that we just created an equation that we can use to solve for x)
Now we solve for x
74 = 2x
step 1 divide each side by 2
74 / 2= 37
2x / 2 = x
we're left with x = 37
Find the circumference of the circle. Use 3.14 for pi
Answer:
A. C = 43.96
Step-by-step explanation:
Circumference = Diameter * pi
Your diameter in this problem (given by the picture) = 14 inches.
If we plug this into the formula:
C = 14 * 3.14 = 43.96
There is a problem with your question, however, because the length we have found is in inches, while all of your options are in centimeters. However, converting the correct inches answers into centimeters is not an answer choice.

Answer:
LMK is 30
Step-by-step explanation:
inside the triangle, the LMN is the equation 3x=90degrees
under the KN is 4x
on the left is 150dgrees = 5x
3x+4x+5x=360
add the x's together
12x=360
divide
x=30
LMK= 150-90/2=60/2=30

One triangle has a weight of 6 grams. What is the weight of one square?
Answer:
Assuming you want them to weigh the same the answer would be 3 grams
Step-by-step explanation:
Because... 6 × 3 = 18 3 × 4 = 12
18 + 12 = 30
6 × 4 = 24 3 × 2 = 6 24 + 6 = 30 therefore
squares = 3
Hope this helps not sure if I am right.
Answer: 3 grames
3 because half of 6 is 3 that’s why and that it is balance so I know they are equal

Answer:
10.5 cm
Step-by-step explanation:
12÷9= 1.3 (1dp)
14÷(12÷9)= 10.5cm
Answer:
y = 10.5 cm
x = 80 degree
Step-by-step explanation:
Our approach is find measures first and y is our missing measure.
To find y
PQRS : ABCD is in ratio the same as CD : RS
We need to work out CD : RS to find measures of AD : SP
To find ratio we look at side measures first
CD : RS = 12 : 9
12/9 = 1.333333
So that AD : SP = 14 : ?
14 / 1.333333 = 10.50000
AD : SP = 14 : 10.5
y = 10.5 cm
To find x
We are given opposite angles and know with quadrilaterals they both share same opposite diagonal length ratios and share same opposite angles.
Where two angles are always in pairs given 100 degree can be multiplied by 2 and use the equation.
360 - (100 x 2) / 2 = (360 - 200) / 2 = 160/2 = 80 degree
x = 80 degree
Which equation describes the relationships
Answer:
Option A
Step-by-step explanation:
Sin(x) is the same value as cos(y) in the graph.
