Answer:
x ≤ 7
Step-by-step explanation:
(2x-4) + 110 ≤ 120
Combine like terms
2x +106 ≤ 120
Subtract 106 from each side
2x+106 -106 ≤ 120-106
2x ≤ 14
Divide each side by 2
2x/2 ≤ 14/2
x ≤ 7
Answer:
59 minutes
Step-by-step explanation:
In the table of values it is observed that for each day of training 2 minutes are increasing and that day 1 begins with 5 minutes of training
, so
, where x= evaluation day
we have to for the day 28
Answer:
x=96°
y=96°
Step-by-step explanation:
y=84° because of vertical angles. the measure of all 4 angles added together is 360°, so we add the 84° and the other 84° angle, and subtract them from 360° to get the sum of the other two angles
360°-(84°+84°)=192°
divide 192° by 2 to get the measure of one angle
therefore, x=96°
Answer:
x = 0
, y = 4
Step-by-step explanation:
Solve the following system:
{y = 4 - 3 x | (equation 1)
x + 2 y = 8 | (equation 2)
Express the system in standard form:
{3 x + y = 4 | (equation 1)
x + 2 y = 8 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x + y = 4 | (equation 1)
0 x+(5 y)/3 = 20/3 | (equation 2)
Multiply equation 2 by 3/5:
{3 x + y = 4 | (equation 1)
0 x+y = 4 | (equation 2)
Subtract equation 2 from equation 1:
{3 x+0 y = 0 | (equation 1)
0 x+y = 4 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 0 | (equation 1)
0 x+y = 4 | (equation 2)
Collect results:
Answer: {x = 0
, y = 4
