Solve for y. 7(x-4)=28
Answer: 8
Step-by-step explanation:
(8 - 4) = 4
so then,
7(8 - 4) = 28
can anyone help me with these questions i will mark you as brainliest
Answer:
X= 38
Step-by-step explanation:
A straight line is 180⁰ so we can subtract that by 133⁰ to get the degree on the inside of the triangle which is 47. You then add 47 and 95 to get 142. To get x you subtract 142 from 180
Important for my exam tomorrow ! Please help
Answer:
Step-by-step explanation:
Adjacent angles of parallelogram are supplementary.
∠A + ∠D = 180
Divide both sides by 2
[tex]\frac{1}{2}[/tex] ∠A + [tex]\frac{1}{2}[/tex] ∠D = 90
∠PAD + ∠ADP = 90 --------------------(I)
IN ΔPAD,
∠PAD + ∠ADP + ∠APD = 180 {angle sum property of triangle}
90 + ∠APD = 180 {from (I)}
∠APD = 180 - 90
∠APD = 90
∠SPQ = ∠APD {vertically opposite angles}
∠SPQ = 90°
Similarly, we can prove ∠PQR = 90° ; ∠QRS = 90° and ∠RSP = 90°
In a quadrilateral if each angle is 90°, then it is a rectangle.
PQRS is a rectangle.
¿Me pueden ayudar con esta ecuación? 9 x + (x - 7) = (5 x + 4) - (8 - 3 x) Es que mi profe dice que es 3/2 pero me sale otra cosa... Gracias <3
Responder:
x = 3/2
Explicación paso a paso:
Dada la ecuación
9 x + (x - 7) = (5 x + 4) - (8 - 3 x)
Debemos encontrar el valor de x que satisface la ecuación
9 x + (x - 7) = (5 x + 4) - (8 - 3 x)
Expandir
9x + x-7 = 5x + 4-8 + 3x
Recopile los términos similares;
9x + x-3x-5x = 4-8 + 7
2x = 3
x = 3/2

2x = 3
x = 3/2
Por lo tanto, el valor de x que hace que la ecuación sea igual es 3/2
Solve this inequality for x: - 3(x + 3) > 30
Answer:
x<-13
Step-by-step explanation:
−3(x+3)>30
Divide both sides by −3. Since −3 is negative, the inequality direction has changed.
x+3<30/-3
Divide 30 by −3 to get −10.
x+3<−10
Subtract 3 from both sides.
x<−10−3
Subtract 3 from −10 to get −13.
x<−13

Write the equation of the line that passes through the points (4,7) and (8,6). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
Step-by-step explanation:
Find Slope: m = [tex]\frac{y_{2-}y_{1} }{x_{2-}x_{1} }[/tex]
m = [tex]\frac{6-(7)}{8-(4)}[/tex]
m = [tex]\frac{-1}{4}[/tex]
Point Slope Form: y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)
plz answer asap and i would be very grateful
hi are u good at rational exponenets? good now help me out
Answer:
Step-by-step explanation:
nth root of a number 'a' is represented by the expression,
[tex]\sqrt[n]{a}[/tex]
In this expression 'n' = Index of of the radical
[tex]\sqrt[4]{16}[/tex] is called the 4th root of 16.
In [tex]\sqrt[4]{16}[/tex], the index is 4 and the radicand is 16.
4th root of 16 can be represented by [tex]\sqrt[4]{16}[/tex]
[tex]\sqrt[4]{16}=(16)^{\frac{1}{4}}[/tex]
[tex]=(2^{4})^{\frac{1}{4}}[/tex]

Mr. Wright needs to buy a water tank for his classroom. The tank must fit inside a storage box that is shaped like a cube with side lengths of 20 feet. Water tanks are available in cylinders, cones, square pyramids, and spheres. Mr. Wright wants to buy the tank that has the largest capacity… What shape should he buy?
Answer:
square pyramids
Step-by-step explanation:
Square pyramids because they have corners and the storage box is shaped like a cube. If he gets things with rounded edges, then there will be empty space between each water tank.

Which kind of triangle exists if the side measures are 3, 9, and 10?
i thought the answer was acute but my teacher marked it wrong and told me the correct answer was obtuse could someone explain why it would be obtuse?
Step-by-step explanation:
There is a rule that if c^2 > a^2 + b^2, then it is an obtuse triangle.
*c is the longest side

Which of these is the algebraic expression for "4 times the sum of 2 and y?"
a 4 ⋅ 2 + y
b 4(2 + y)
c 2 + 4 ⋅ y
d 2(4 + y)
Answer:
b
Step-by-step explanation:
The sum of 2 and y is 2 + y, then 4 times this sum is
4(2 + y) → b

Find the inverse equation of y=3x-12
Answer:
[tex]f {}^{ - 1}(x) = \frac{x}{3} + 4[/tex]
Step-by-step explanation:
[tex]y = 3x - 12[/tex]
Flip the variables then solve for y
[tex]x = 3y - 12[/tex]
[tex] \frac{x}{3} = y - 4[/tex]
[tex] \frac{x}{3} + 4 = y[/tex]
[tex]f {}^{ - 1} (x) = \frac{x}{3} + 4[/tex]
Andrew is paid £250 a week. Each week, he shares his pay with his sister in the ratio 3 : 2 saves 12% of his share. How many weeks will it take Andrew to save £360?
Answer:
20 weeks
Step-by-step explanation:
The computation of The number of weeks it will take to save £360 is shown below:
Now $250 should be divided into a ratio of 3:2
He keeps = 150
ANd, he gives her = 100
As he saves 12% of his share
i.e.
= 12% of 150
= 18
Now the number of weeks would be
= 360 ÷ 18
= 20 weeks
