Answer:
22x + 21y = 0
Step-by-step explanation:
33x + 22y = 11x + y
Subtract y from both sides.
33x + 21y = 11x
Subtract 11x from both sides.
22x + 21y = 0

Answer:
∠ V = 58°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ WYX = 180° - (52 + 24)° = 180° - 76° = 104°
∠ VYU = ∠ WYX = 104° ( vertically opposite angles )
Then
∠ V = 180° - (104 + 18)° = 180° - 122° = 58°
i really need help with this since it’s practice for my midterms
Answer:
It is D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Evaluate the fractions inside the absolute value
2 [tex]\frac{5}{6}[/tex] + [tex]\frac{7}{4}[/tex] ( change mixed number to improper fraction )
= [tex]\frac{17}{6}[/tex] + [tex]\frac{7}{4}[/tex] ( the LCM of 6 and 4 is 12 ) , then
= [tex]\frac{17(2)}{6(2)}[/tex] + [tex]\frac{7(3)}{4(3)}[/tex]
= [tex]\frac{34}{12}[/tex] + [tex]\frac{21}{12}[/tex] ( add the numerators, leaving the common denominator )
= [tex]\frac{55}{12}[/tex]
= 4 [tex]\frac{7}{12}[/tex] → D
Identify the like terms in the equation 2/9 x + 6/7 + 2.35x = -4/5 x.
Answer:
Step-by-step explanation:
2/9 x + 6/7 + 2.35x = -4/5 x.
the like terms are 2/9 x , 2.35x, and -4/5 x.
they all have the variable x
given that f(m) = m/2, find m
Answer:
let f(m) = u
multipling both sides by 2
We have 2f(m)=m
therefore m=2
2. Sum of two numbers = 16
Difference of the numbers = 6
Find the numbers.
What is their product?
Answer:
Step-by-step explanation:
let the numbers be x and y.
x+y=16
x-y=6
add
2x=22
x=22/2=11
11+x=16
x=16-11=5
product xy=11×5=55
Give the equation for a circle with the given center and radius.
Center at (2, -9), radius = 3
A. (x+2)^2+(y−9)^2=9
B. (x+9)^2+(y−2)^2=3
C. (x−9)^2+(y+2)^2=3
D. (x−2)^2+(y+9)^2=9
Answer:
(x-2)^2 + (y+9)^2 = 9
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-2)^2 + (y--9)^2 = 3^2
(x-2)^2 + (y+9)^2 = 9
Answer:
D.) (x−2)2+(y+9)2=9

the answer will be
1.2x10⁴
hope it helps
Answer:
We have been provided the number, 3430000. Therefore, the standard form is, 3430000=3.43×106, here, we have moved 6 places to the left. Hence, the standard form of 3430000 is 3.43×106. Note: It is important to note that the standard form of representing numbers is also called scientific form or standard index form.
Which monomials are perfect squares? Select three options.
a
25x12
b
16x9
c
6x2
d
36x16
e

Total mass = 8 kg
Mass of tool 1 = 4 kg
Mass of tool 2 = 2 kg
So,
Total mass = Mass of tool 1 + Mass of tool 2 + Mass of tool 3
=> 8 kg = 4 kg + 2 kg + Mass of tool 3
=> 8 kg = 6 kg + Mass of tool 3
=> 8 kg - 6 kg = Mass of tool 3
=> 2 kg = Mass of tool 3

Solve the simultaneous equation, will give out brainliest answer
a=bcd
a+b=cd
a+b+c=d
a+b+c+d=1
Answer:
a=1/2,b=-1,c=-1 and d=1/2
Am I right please?
Answer:
a = 1/42; b = 1/7; c = 1/3; d = 1/2
Step-by-step explanation:
a = bcd
a + b = cd
a + b + c = d
a + b + c + d = 1
d + d = 1
2d = 1
d = 1/2
2a = bc
2a + 2b = c
2a + 2b + 2c = 1
bc + 2b = c
bc + 2b - c = 0
bc + 2b + 2c = 1
-3c = -1
c = 1/3
a + b = cd
a + b = 1/6
a = bcd
a = b(1/3)(1/2)
a = 1/6 b
1/6 b + b = 1/6
7/6 b = 1/6
b = 6/42
b = 1/7
a = 1/6 b
a = 1/6 * 1/7
a = 1/42
To paint a wooden cube, Pinocchio needs 4 grams of paint. When it is dry, he cut the cube into 8 smaller pieces of smaller size. How much paint additional paint does Pinocchio need to paint the unpainted surfaces of the smaller cubes
Answer:
9 grams of paint
Step-by-step explanation:
6×8=48
48÷4= 12
48-12=36
36÷4=9
first multiply 6 by 8 because a cube has six faces and you cut that cube eight times
second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted
next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted
lastly you divide 36 by 4 and you will get 9 grams of paint
A recipe requires 500 mL of milk. You will make the recipe once a month for the next 4 months. You do not use milk other than for cooking. Which container of milk should you buy? (1L=1000 mL) *
Answer:
2L
Step-by-step explanation:
Each recipe = 500 mL of milk
Number of times you make recipe per month = 1
Number of months you make recipe = 4
Total milk used for 4 months = 500 mL * 1 * 4
= 2000 mL
Recall,
1L = 1000 mL
Therefore,
2000 mL = 2L
You should buy 2L container of milk
