Solve for x by simplifying both sides of the equation, then isolating the variable.
Landon has 76 dinosaurs, but he gives his sister 13 of them to play with. Then he put his dinosaurs into 9 groups. How many dinosaurs are in each group?
Answer:
7 groups
Step-by-step explanation:
76-13 is 63
63 divided by 9 is 7
Answer:
7
Step-by-step explanation:
Subtract 13 dinosaurs from the 76 original dinosaurs
76-13 = 63
Now divide them into 9 groups
63/9 = 7
There are 7 dinosaurs in each group

Can the sides of a triangle have lengths 7, 12, and 18?
Answer:
Yes
Step-by-step explanation:
By the Triangle Inequality Theorem, if a supposed triangle has sides [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] where [tex]c[/tex] is the longest side, then [tex]a+b\geq c[/tex].
Here, [tex]7+12\geq18[/tex], so the given sides of the triangle can have these lengths

The points N(-4,3)(−4,3), O(-4,-3)(−4,−3), and P(5,3)(5,3) form a triangle. Plot the points then click the "Graph Triangle" button. Then find the perimeter of the triangle. Round your answer to the nearest tenth if necessary.
The perimeter of the triangle = 25.8 units.
What is the Perimeter of a Triangle?Perimeter = the sum of the length of all three sides
Given:
N(-4,3)
O(-4,-3)
P(5,3)
Perimeter of triangle NOP = NO + OP + NP
Find NO:
NO = |3 - (-3)| = 6 units
Find NP:
NP = |-4 - 5| = 9 units
Using the distance formula, find OP:
OP = 10.8 units
Therefore, Perimeter of the triangle = 10.8 + 9 + 6 = 25.8 units.

Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7
Curved surface area of cylinder = 2 πr h
= 2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)
= 440 cm²
So, the curved surface area of cylinder is 440 cm²

5. What is the distance from V to W? V=8 cm W 15 cm m<VW= 90
Answer:
17 cm
Step-by-step explanation:
If the angle between V and W is 90°, then this implies that V and W are legs of a right triangle (and the distance between them is the hypotenuse).
Use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse of a right triangle.
Let D = distance between V and W:
⇒ V² + W² = D²
⇒ 8² + 15² = D²
⇒ 289 = D²
⇒ D = √289
⇒ D = 17
Therefore, the distance from V to W is 17 cm
[tex]\huge \boxed{\sf 17\ cm}[/tex]
Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides.
[tex]\sf a^2 + b^2=c^2\\\\8^2 + 15^2=c^2\\\\ \sqrt{8^2 + 15^2} =c\\\\17=c[/tex]
The price for 3 protein bars $3.75, and the price of 3 fruit cups is $1.50. Write the equation
that represents the relationship between the number of protein bars, x, and fruit cups, y,
that you can buy with $15.50.
How many fruit cups can you buy with 4 protein bars?
Answer:
7 fruit cups
Step-by-step explanation:
$3.75/3x + $1.50y = $15.50
So, if you have 4 protein bars, the equation would read:
1.25x + 1.5y = 15.5
1.25(4) + 1.5y = 15.5
5 + 1.5y = 15.5
1.5y = 10.5
y = 7

Step-by-step explanation:
A CEO wondered if her company received either more or less complaints from its workers on Monday than any other day. She figured that if it were truly random, 20% of the complaints should have been filed on Monday. She randomly selected 50 complaints and checked the day that they were submitted. In those complaints 13 were submitted on a Monday. The CEO conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of complaints submitted on a Monday is different from 20%.

Milo is making 1 1/2 batches of muffins for a bake sell. If each batch of muffins calls for 1 3/4,how many cups of flour will he need ?
Answer:
2 5/8
Step-by-step explanation:
Because she has one whole batch of cookies that will require 1 3/4 of flour. Since the remainder is a 1/2 batch, you would have to half the 1 3/4. Halfing 1 3/4 is 7/8. You add 1 3/4 + 7/8 and you get 2 5/8.

solve: y = 3x - 4
y = x + 2
Answer:
y = 5
Step-by-step explanation:
Isolate x to plug in to other equation
y = x + 2
-y-x -y-x
(- x = -y + 2) / -1
x = y - 2
Plug into other equation
y = 3(y-2) - 4
Distribute
y = 3y-6-4
y = 3y-10
-3y -3y
(-2y = -10)/-2
y = 5
