Answer:
3.82 cm tall.
Step-by-step explanation:
Alexander measures a stack of textbooks to be 38.2 cm tall. If there are 10 textbooks in the stack, how tall is each textbook?
From the above question:
1 stack = 10 textbooks = 38.2 cm tall
Hence,
10 textbooks = 38.2 cm tall
1 textbook = x cm
Cross Multiply
10 x = 1 × 38.2
x = 38.2/10
x = 3.82 cm tall
Therefore, each textbook is 3.82 cm tall.
Answer:
x ≥ 12
Step-by-step explanation:
-3/4x +2 ≤ -7
Subtract 2 from each side
-3/4x +2-2 ≤ -7-2
-3/4x ≤ -9
Multiply each side by -4/3, remembering to flip the inequality
-3/4x * -4/3 ≥ - 9 *(-4/3)
x ≥ 12
Answer:
$5.50
Step-by-step explanation:
$8.25/3=2.75
2.75=1 ice cream cone
2 ice cream cones=2.75+2.75
2 ice cream cones=5.50

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°
