Answer:
x=21
Step-by-step explanation:
Hello There!
In order to find the value of x we need to find the value of y
The angle labeled y and the right angle are vertical angles with the angle labeled 5y +10 therefore they are congruent
so y+90=5y+10
step 1 subtract y from each side
5y-y=4y
now we have
90=4y+10
step 2 subtract each side by 10
90-10=80
now we have
80=4y
step 3 divide each side by 4
80/4=20
so y =20
now we plug in y to (5y+10)
5x20=100
100+10=110
So now we can find x
The angle labeled 3x+7 is supplementary with the angle that is equal to 110
meaning that the sum of the two angles equal 180
so 180 = 3x+110+7
step 1 combine like terms
110+117
now we have
180=3x+117
step 2 subtract each side by 117
180-117=63
now we have 3x=63
step 3 divide each side by 3
63/3=21
so we can conclude that x = 21
Answer:
x = 21°
Step-by-step explanation:
y = 180° - 90° - (3x+7)°
y = 83° - 3x
(5y + 10) and (3x + 7) are supplementary angles (their sum is 180°) so:
(5y + 10) + (3x + 7) = 180°
reduce:
5y + 3x = 163°
substitute for y:
5(83° - 3x) + 3x = 163°
415° - 15x + 3x = 163°
reduce:
-12x = -252
divide both sides by -12:
x = 21°
y = 83° - 3(21°) = 20°
check:
(5(20) + 10) + (3(21) + 7) = 180°
110° + 70° = 180°

Marsha is buying plants and soil for her garden. The soil cost $4 per
bag, and the plants cost $10 each. She wants to buy at least 5 plants
and can spend no more than $100. Write a system of linear
inequalities to model the situation.
Answers
Answer:
p ≥ 5
4s + 10p ≤ 100
Step-by-step explanation:
Here, we want to write a system of inequalities
Let the number of bags of soil be s and the number of plants be p
She wants to buy at least 5 plants
mathematically, when something is at least 5, it means greater than or equal to 5
In inequality, we have this as;
p ≥ 5
Secondly, she wants to spend not more than $100; she can spend less but cannot spend more
We have this as;
The number of bags she can buy at $4 per bag is 4 * s = 4s
the number of plants at $10 per one will be;
10 * p = 10p
Adding both should give a cost less than or equal to 100
We have this as;
4s + 10p ≤ 100
So, we have the system of inequalities as;
p ≥ 5
4s + 10p ≤ 100

14. Given that log 2 = 0.3010 and log 3 = 0.4771 , how can we find log 6 ?
A. log6 = log2 x log3 = 0.3010 x 0.4771
B. log6 = log2 + log3 = 0.3010 + 0.4771
C. log6 = log2 – log3 = 0.3010 – 0.4771
D. log6 = log2 = log3 = 0.3010 = 0.4771
Answers
Answer:
B. log6 = log2 + log3 = 0.3010 + 0.4771
Step-by-step explanation:
log 2 = 0.3010
log 3 = 0.4771
log 6 = ?
6 = 3 * 2
log 6 = log (3 * 2)
According to log rules;
log (a * b) = log(a) + log (b)
This means;
log 6 = log 3 + log 2
Inserting the values they represent;
log 6 = log 3 + log 2 = 0.4771 + 0.3010
Correct option:
B. log6 = log2 + log3 = 0.3010 + 0.4771
6.00+1.50(m)=26.25 find what m is
Answers
Answer:
13.5
Step-by-step explanation:
first let's subtract 6.00 from 6.00 and 26.25
26.25-6=20.25
1.50(m)=20.25
so we need to get rid of the 1.50
so 1.50m divided by 1.50=m
20.25÷1.50=13.5
m=13.5 hope this helps

Answers
Answer:
x = 0
Step-by-step explanation:
24 - (3x - 9) - 6 = -2(4x - 10) + 5x + 7
solve the brackets by using the distribute property:
1(3x - 9) = 3x - 9
-2(2x - 10) = -8x + 20
rewrite the equation:
24 - 3x - 9 - 6 = -8x + 20 + 5x + 7
combine like therms:
27 - 3x = -3x + 27
subtract 27 from both sides:
27 - 3x - 27 = -3x + 27 - 27
- 3x = -3x
add x to both sides of the equation:
-3x + 3x = -3x + 3x
x = x or 0 = 0
to check, substitute 0 for x
24 - (3(0) - 9) - 6 = -2(4(0) - 10) + 5(0) + 7
anything times 0 is 0
24 - (0 - 9) - 6 = -2(0 - 10) + 0 + 7
solve:
24 + 9 - 6 = 0 + 20 + 0 + 7

What is the relationship between the exterior angle of a triangle and its remote
interior angles?
Answers
Answer:
The sum of the interior angles of a triangle is always 180 degrees. The exterior angle is the angle between any side of a shape, and a line extended from the next side. The sum of an exterior angle and its adjacent interior angle is also 180 degrees.
The relationship between the exterior angle of a triangle and its remote
interior angle is the exterior angle is equal to the sum of the two remote interior angles.
Which is known as the Exterior Angle Theorem.
What is a triangle?
A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
In a triangle, the exterior angle is formed when one side of the triangle is extended.
The exterior angle and the two remote interior angles (angles adjacent to the exterior angle on the triangle) form a linear pair, which means they add up to 180 degrees.
More specifically, the exterior angle is equal to the sum of the two remote interior angles.
This relationship is known as the Exterior Angle Theorem, which states that the measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.
For example, if one of the remote interior angles of a triangle measures 40 degrees, and the exterior angle adjacent to it measures 120 degrees, then the other remote interior angle measures 180 - 40 - 120 = 20 degrees.
Thus,
The relationship between the exterior angle of a triangle and its remote
interior angle is the exterior angle is equal to the sum of the two remote interior angles.
This relationship is known as the Exterior Angle Theorem.
