A painter needs 5 gallons of paint to finish a house. He has 3 quarts and 1 pint. How much more paint does he need
Answer:
Step-by-step explanation:
He needs 1 pint to get the 3 quarts to 4 quarts.
4 quarts = 1 gallon.
So if he buys 1 pint he will have 1 gallon.
He needs 5 gallons.
He has 1 gallon
He needs 5 - 1 = 4 gallons.
Answer: he needs 1 pint and 4 gallons.

Which system of equations has the same solution as the system of
equations shown below?
6x + 2y = 10
8x + 4y = 12
Answer:
b
Step-by-step explanation:
that's what my teacher said.
6x + 2y = 10 and -4x=-8 system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations are
6x+2y=10..(1)
2y=10-6x...(2)
We need to find system of equation which having same solutions as above.
From equation (2)
y=5-3x
Now substitute y value in equation 1.
8x+4(5-3x)=12
8x+20-12x=12
-4x=12-20
-4x=-8
Hence, 6x + 2y = 10 and -4x=-8 system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12

Which postulate proves these two
triangles are congruent?
A. HL
B. SSA
C. SAS
D. None, not congruent
SAS is the postulate that establishes the congruence of these two triangles.
What is meant by triangle?The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles. According to the Angle-Side-Angle Postulate (ASA), if two angles from one triangle and its included side are congruent with two angles from another triangle and its included side, then the two triangles are congruent. Three sides and three vertices make up a triangle, which is a polygon. There is a 180 degree angle created inside the triangle. In other words, a triangle's internal angles add up to 180 degrees.To learn more about triangle, refer to:

Step-by-step explanation:
(x+16)=(4x-5)
Subtract x from both sides
16=3x-5
Add 5 to both sides
21=3x
Divide both sides to get x=7
Both angles are congruent due to the vertical angles theorem which states that if angles are vertical then they are congruent.

What is the measure of angle KLM
Answer:
In triangle KLM, the measure of angle K is 119 degrees, KL=23, and KM=20.
The measurement of the angle KLM is 64°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of ∠KLM,
Here,
∠KLM + ∠KLJ = 180° [linear pair]
20x+4 + ∠KLJ = 180°
∠KLJ = 176-20x
Consider the triangle, KLJ,
∠KLJ + ∠KJL + ∠JKL = 180° [sum of the interior angles of a Δ)
8x+18+6x+4+176-20x = 180°
-6x = -18
x = 3
So, ∠KLM = 20(3)+4 = 64°
Hence, the measurement of the angle KLM is 64°.

when time in hours (t) increases, how does distance in km (d) change?
Question seems incomplete but will be explained with assumptions
Answer and explanation:
If for example, a car travels 30 km per hour, then it would travel 60km in 2 hours and 90km in 3 hours and so on
We can apply the formula for distance as such:
Distance(d)= Speed(s) × time(t)
d=st
Where d is distance travelled say 60km
S is speed= 30km/hr
Time = 2 hrs
Also to calculate speed when distance and time is given, we can make speed the subject of the formula:
s=d/t
To calculate time when distance and speed are given, we can make time the subject of the formula:
t=d/s
198 woman to 110 men in the simplest form
Answer:
1 4/5
Step-by-step explanation:
198 woman to 110 is basically a ratio, so we should put it like this: 198:110
Now, a ratio that needs to be simplified is basically a fraction, so: 198/110
Now we divide the fraction.
First, find the GCF of both numbers.
The GCF of 198 and 110 are both 22.
Now we divide, and we get 9/5, and we turn it into a mixed number, 1 4/5.
