2x+5y=619
x=10y-3
________
2(10y-3) +5y=619
20y-6+5y=619
25y=619+6
25y=625
y=625/25
y=25
x=10*25-3
x=250-3
x=247
The measure of length SV is 60 units
<h3>Isosceles Right Triangle</h3>
An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.
The above means that:
Substitute values for SV and ST
Subtract z from both sides
From the figure, we have:
Substitute 30 for z
Hence, the measure of length SV is 60 units

Answer:
(b) x ≤ -4
Step-by-step explanation:
There are a few things to note when reading an inequality on a number line.
The number line would contain the following:
i. <em>circles</em>: These can be closed or open. Closed circles are denoted by a shaded small circle showing that the point or number shown on the number line is included in the inequality. Open circles are denoted by an unshaded small circle showing that the point or number shown on the number line is not included in the range of inequality.
ii. <em>arrows</em>: An arrow can point to the right or left. When it points to the right, that means the values greater than the number specified on the number line are included in the range. When it points to the left, the values less than the number are included.
From the given number line,
The type of circle is a closed circle since it is shaded. This means that the number pointed at on the number line (-4 in this case) is included in the range.
Also, the arrow is pointing leftwards. This means that values less than the number pointed at (-4 in this case) are included in the range.
Therefore, the inequality should read,
x ≤ -4
This shows that all values of x less than or equal to -4 are included in the range.
Answer:
Radius = 4.95 cm
Step-by-step explanation:
I am assuming you need the radius of the base of the cylinder.
Volume = 1.54 * 1000 = 1540 cm^3
Volume = πr^2h so:
1540 = π*r^2*20
r^2 = 1540/20 π = 24.510
r = 4.95 cm.
