Answer:
Nancy will be 32 and Khaled will be 16
Step-by-step explanation:
3 years ago Nancy was more than 2 so lets start with 2. To get back to present each year x2 meaning 3 x 2=6 and add the 2 so thats 8. Now the 4 more years is 4x2 which is 8. 8+8=16 and then twice Nancy's age is 16x2: Nancy is 32 and Khaled is 16
What are the like terms in the expression
below?
3x + 8 + 3y + 8x
A 8 and 8x
C3x and 8x
B 3x and 3y D 3x, 3y, and 8x
Answer:
c) 9x and 8x
Step-by-step explanation:
3x + 8 + 3y + 8x
the like terms are 3x and 8x since they both have the same variables
8 and 3y are not the like terms because there's no other number with the same variable as them.

Given isosceles right triangle CDE with m∠D = 90, sin C = sin D
Answer:True
Step-by-step explanation:
Given
[tex]\angle D=90^{\circ}[/tex]
For isosceles triangle , CD=DE (x=y)
from figure,
[tex]\sin C=\dfrac{y}{H}\\\\\sin D=\dfrac{x}{H}\\\\\text{CD=DE}\\\\\therefore \sin C=\sin D=\dfrac{x}{H}=\dfrac{y}{H}[/tex]
Thus, the given statement is true

A plane travels 3400 miles in 8 hours. How far would it travel in 6 hours at this rate? What is the Unit Rate: Write the equation: How far will the plane travel in 6 hours: (disance in miles)
Answer:
Unit rate 425 miles/hr, equation: m = 425h, in 6 hours plane will travel 2550 miles
Step-by-step explanation:
Set up a proportion, so 3400/8 = x/6 so x = 2550

In January, a puppy weighed 4kg.
Three months later, the same puppy weighed 5kg.
What was the percentage increase in the puppy's weight?
Answer:
25%
Step-by-step explanation:
5kg=5000g(a)
4kg=4000g(b)
p=percent
a=b+bxp/100
5000=4000+4000xp/100
5000-4000=40xp
1000=40xp
p=1000/40
p=25
R:25%
The percentage increase in the puppy's weight is 25% and this can be determined by using the unitary method.
Given :
In January, a puppy weighed 4kg. Three months later, the same puppy weighed 5kg.The following steps can be used to determine the percentage increase in the puppy's weight:
Step 1 - The unitary method can be used to determine the percentage increase in the puppy's weight.
Step 2 - According to the given data, in January, a puppy weighed 4kg. Puppy's weight is 4kg in January which is 100%.
Step 3 - So, if 4 kg is 100% then 5kg is equal to:
[tex]=\dfrac{100}{4}\times 5[/tex]
Multiply 100 by 5 in the above expression.
[tex]=\dfrac{500}{4}[/tex]
Divide 500 by 4 in the above expression.
= 125%
Step 4 - So, the percentage increase in the puppy's weight is:
= 125 - 100
= 25%

Help me PLEASE quick I will give you brainliest
Answer:
56. Someone correct me if I'm wrong.
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem, which is a² + b² = c²
a and b are the legs, and c is the hypotenuse. Here, we know the length of one leg and the hypotenuse. So...
a² + 42² = 70²
First, we need to square these numbers. 42² is 1764. 70² is 4900. So...
a² + 1764 = 4900
Now, we can subtract 1764 from both sides.
a² + 1764 - 1764 = 4900 - 1764
That would give us...
a² = 3136
Now, we square root 3136.
So...
[tex]\sqrt{3136}[/tex] = 56
The missing side should be 56.

y

x
If
y
=
45
when
x
=
81
find,
y
when
x
=
225
Answer:
y = 75
Step-by-step explanation:
Given that:
y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]
⇒ y = k[tex]\sqrt{x}[/tex]
where k is the constant of proportionality.
When y = 45, x = 81, then;
45 = k[tex]\sqrt{81}[/tex]
45 = 9 k
k = [tex]\frac{45}{9}[/tex]
= 5
k = 5
So that,
y = 5[tex]\sqrt{x}[/tex]
the value of y when x = 225 is;
y = 5[tex]\sqrt{x}[/tex]
= 5 x [tex]\sqrt{225}[/tex]
= 5 x 15
y = 75

We are given an expression and are asked to solve, when solving, we need to follow the PEMDAS rule. Commonly used when so many factors and signs are at hand.
PEMDAS -
Parenthesis
Exponents
Multiply
Divide
Addition
Subtraction
This rule is showing what to do first when you have long expressions like these, do as followed and solve the parenthesis first :
7 + (16 - 7) / 3 + 8
7 + 9 / 3 + 8
Now divide :
7 + 9 / 3 + 8
7 + 3 + 8
Now that we only have to add, add all numbers together :

Answer:
Slope.
Step-by-step explanation:
mx+b
Answer:
Slope
Step-by-step explanation:
The equation of lines are normally formatted in "slope-intercept form"
(y = mx + b)
The b in the equation would be the y-intercept of the line.
The m represents the slope.
The x and y can be replaced with any x and y value from the line (if necessary)

Find the value of x.
please help
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees
