Answer:
∠A=67°
∠B=70°
∠C=43°
Step-by-step explanation:
<u><em>The correct question in English is</em></u>
Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.
we know that
The measure of the interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
substitute the given values
solve for x
Find the measure of each angle
∠A=(3(22)+1)=67°
∠B=(3(22)+4)=70°
∠C=(2(22)-1)=43°
The completion of the grouped frequency distribution for the test scores of the fifteen students that took the biology test last week is as follows:
Test scores Frequency

89 to 93 6
94 to 98 2
<h3>What is a frequency distribution?</h3>
A frequency distribution is a pictorial or graphical representation that shows the number of observations of each categorical value (a group of values) that occurs.
By showing the frequency counts for each category, it becomes easier to determine and interpret the presented information based on their relative frequencies.
Frequency charts, tables, or graphs are used to display frequency distributions of data.

Answer:
V = D/M
Step-by-step explanation:
divide both sides by M to isolate V
Answer:
y=-2x+3
Step-by-step explanation:
equation for slope is y=mx+b
the slope is -2 so that equals m
(0,3) is the y-intercept
y=b
3 is the y value making it substitute b making the equation y=-2x+3
